The notion of a rough set is an extension of set theory. The notion of set theory such as intersection and union can be applied in rough sets. The properties of the rough set in detail were introduced by Pawlak in 1982. The construction of notions in algebraic structures is motivated by set theory. This is also done in rough sets so that a notion called rough algebraic structures is obtained. Some concepts of rough algebraic structures that have been constructed include rough groups, rough rings, and rough modules. Furthermore, in multilinear algebra, we know the concept (R, S) - bimodules. Motivated by the relationship of the concept of the rough sets with algebraic structures, this paper aims to provide a definition (R, S) -bimodules in rough algebra, namely by replacing the R and S rings with the rough rings R
1 and S1 . Furthermore, we will give some examples of (R1 , S1 ) -rough bimodules and it will also be shown that some of the properties (R1 , S1 ) -bimodules still apply in (R1 , S1 ) -rough bimodules. On the other hand, we will also give the definition of rough bisubmodules and the homomorphism of rough bimodules. [ABSTRACT FROM AUTHOR]- Published

ALGEBRA ,LIE algebras - Abstract
For a given Lie algebra L, the main problem about local 1 2 -derivations is to prove that they automatically become an 1 2 -derivation or to give examples of local 1 2 -derivation of L, which are not 1 2 -derivation. In this paper, we investigate local 1 2 -derivations on quasi-filiform Leibniz algebras. It is proved that quasi-filiform Leibniz algebras of type I, as a rule, admit a local 1 2 -derivation which is not 1 2 -derivation. [ABSTRACT FROM AUTHOR]

The focus of this paper is to examine 2-local automorphisms of the Arens algebra L
ω (M,τ)) that is connected to a von Neumann algebra. Consider a von Neumann algebra M of type I accompanied by a trustworthy, regular, and semi-finite trace τ, we consider the noncommutative Arens algebra L ω (M , τ) = ∩ p ≥ 1 L p (M , τ) , where Lp (M,τ) is a Banach space defined Lp (M,τ)={x ∈ S(M,τ) :τ (| x |p )<∞} for p≥1. We will show that the surjective 2-local involutive automorphism Φ of the Arens algebra Lω (M,τ) identically acting on the center is an inner automorphism, i.e. there is a unitary element u of the Arens algebra Lω (M,τ) such that Φ(x)=uxu* for all x ∈ Lω (M,τ). It is required that the automorphism ϕx, y (x) for an arbitrary pair (x, y), satisfying the conditions ϕx, y (x)=Φ(x) and ϕx, y (y)=Φ(y), acts identically on the center of the Arens algebra.

SEED harvesting ,K-theory ,EXPOSITION (Rhetoric) ,RESONATORS ,ALGEBRA - Abstract
Frieze groups are discrete subgroups of the full group of isometries of a flat strip. We investigate here the dynamics of specific architected materials generated by acting with a frieze group on a collection of self-coupling seed resonators. We demonstrate that, under unrestricted reconfigurations of the internal structures of the seed resonators, the dynamical matrices of the materials generate the full self-adjoint sector of the stabilized group C*-algebra of the frieze group. As a consequence, in applications where the positions, orientations and internal structures of the seed resonators are adiabatically modified, the spectral bands of the dynamical matrices carry a complete set of topological invariants that are fully accounted by the K-theory of the mentioned algebra. By resolving the generators of the K-theory, we produce the model dynamical matrices that carry the elementary topological charges, which we implement with systems of plate resonators to showcase several applications in spectral engineering. The paper is written in an expository style. [ABSTRACT FROM AUTHOR]

We consider the quantum Gelfand invariants which first appeared in a landmark paper by Reshetikhin et al. [Algebra Anal. 1(1), 178–206 (1989)]. We calculate the eigenvalues of the invariants acting in irreducible highest weight representations of the quantized enveloping algebra for g l n . The calculation is based on Liouville-type formulas relating two families of central elements in the quantum affine algebras of type A. [ABSTRACT FROM AUTHOR]

In this paper, we investigate the affine ageing algebra a g e ̂ (1) , which is a central extension of the loop algebra of the one-spatial ageing algebra a g e (1). Certain Verma-type modules including Verma modules and imaginary Verma modules of a g e ̂ (1) are studied. Particularly, the simplicity of these modules are characterized and their irreducible quotient modules are determined. We also study the restricted modules of a g e ̂ (1) which are also the modules of the affine vertex algebra arising from the one-spatial ageing algebra a g e (1). We present certain constructions of simple restricted a g e ̂ (1) -modules and an explicit such example of simple restricted module via the Whittaker module of a g e ̂ (1) is given.

ALGEBRA ,SUPERALGEBRAS ,ISOMORPHISM (Mathematics) - Abstract
In this paper, we introduce a family of functors denoted as F b , which act on algebraic D-modules and produce modules over N = 2 superconformal algebras. We demonstrate that these functors preserve irreducibility for all values of b, except for explicitly outlined cases. Moreover, we establish the necessary and sufficient conditions for determining the natural isomorphism between two such functors. Our constructed functors recover specific irreducible modules over N = 2 superconformal algebras, including intermediate series and U (h) -free modules. Additionally, we show that our constructed functors yield several new irreducible modules for N = 2 superconformal algebras. [ABSTRACT FROM AUTHOR]

We consider genetic and evolution algebras generated by non-ergodic Volterra operator. It is known that a zero-sum game generated by Volterra operator be a RPS game if and only if the operator is a non-ergodic transformation. We will call the genetic (evolution) algebra generated by non-ergodic Volterra operator RPS genetic (respectively RPS evolution) algebra. In this paper, we investigate the problem of isomorphism of two RPS genetic (evolutionary) algebras and establish necessary and sufficient conditions when two such algebras will be isomorphic.

In the paper local and 2-local *-automorphisms on real algebra B(X) of all bounded linear operators on a real Banach space are considered. In particular, 2-local *-automorphisms of real W*-algebra B(H

Moreover, it is proved that if X is a real Banach spaces and θ : B(X)→B(X) is a local automorphism, then θ is an automorphism. [ABSTRACT FROM AUTHOR]- Published

Proof is important in mathematics both as a component of mathematics and as a mathematics learning tool. The ability to construct proof is one indicator of mathematical reasoning, which is a critical component of mathematics learning outcomes, particularly in Algebra. This research aims to describe the students' mathematical proving ability. This design research consists of three stages: preparing for the experiment, the design experiment, and the retrospective analysis. Focus discussion of this paper is only students' mathematical proving ability in the design experiment and the retrospective analysis. This research involved 9 students of mathematics education. The test (post-test) was conducted to collect data about students' mathematical proving ability. This research resulted in a Local Instruction Theory (LIT) of learning algebra proofs which contains 4 activities: reading proof, completing proof, examining proof, and constructing the proof. In the experiment activities, students experienced the common errors, such as assuming the conclusion to prove the conclusion, proving general statements using specific examples, not proving both conditions in a bi conditional statement, and misusing definitions. The common errors Student errors are reduced after all activities are completed. The result of this research showed that mathematical proving ability can be categorized into three score categories, low, middle, and high level. From 9 students involved in this research: 2 students in high level and 7 students in low level or 2 students in high score category, 5 students in middle score category, and 1 student in low score category.

ASSOCIATIVE algebras ,ALGEBRA ,LIE algebras ,COHOMOLOGY theory - Abstract
The notion of O -operator is a generalization of the Rota–Baxter operator in the presence of a bimodule over an associative algebra. A compatible O -operator is a pair consisting of two O -operators satisfying a compatibility relation. A compatible O -operator algebra is an algebra together with a bimodule and a compatible O -operator. In this paper, we construct a graded Lie algebra and an L
∞ -algebra that respectively characterize compatible O -operators and compatible O -operator algebras as Maurer–Cartan elements. Using these characterizations, we define cohomology of these structures and as applications, we study formal deformations of compatible O -operators and compatible O -operator algebras. Finally, we consider a brief cohomological study of compatible dendriform algebras and find their relationship with the cohomology of compatible associative algebras and compatible O -operators.

Fuzzy mathematics is an area of mathematics concerned with fuzzy set theory and fuzzy logic. The description provided by fuzzy sets is more accurate than the description provided by conventional sets. The paper highlights a bunch of new fuzzy mathematics approaches. The structure of Algebra G-fuzzy metric space (AGFM-space) was introduced, a new type for the concept of G-fuzzy metric space, gives a consistent extension of G-metric space, and leads to further investigations and applications. A condition was proposed for a G*-convergence sequence in the suggested area to be G*-Cauchy. Moreover, some enhanced versions of theoretical applications in AGFM-spaces are developed.

VALUATION ,ALGEBRA ,MEASUREMENT - Abstract
This paper is motivated by GABOR SZASZ's introduction of outer measure based on valuation for lattices. We introduce order-preserving valuation on a relative sub lattice of the lattice, a countable cover of an element in a relative sub lattice, outer measure induced by a valuation of a relative sub lattice, Ɲ* measurability and to establish certain elementary properties of induced outer measure via order preserving valuation on a relative sub lattice. To prove outer measure via order preserving valuation on a relative sub lattice is also valid the outer measure generated by measure, we define the definition of outer measure on relative sub lattices of a lattice L induced by a measure Ɲ on Q of relative sub lattices of L, measure on algebra of relative sub lattices and outer measure of relative sub lattices, we prove L(ℬ) is a sigma-algebra where L(ℬ) is the class of Ɲ* measurable relative sub lattices and deduce a corollary that Ɲ*(S) = Ɲ(S), also we prove that outer measure to any subset E of a relative sub lattice SEQ
σ and outer measure to relative sub lattice BEQσδ are equal. Finally, by defining sigma-finite measure on Q and Ɲ* generated by Ɲ we prove a relative sub lattice E is measurable Ɲ* ⇔ E is the proper difference S ∼ B of a relative sub lattice A in Qσδ and a relative sub lattice B with Ɲ*(B) = 0. Further each relative sub lattice B with Ɲ*(B) = 0 is contained in a relative sub lattice C in Qσδ with Ɲ*(C) = 0. [ABSTRACT FROM AUTHOR]- Published

We use the constraints to evaluate the R (p , q) -differential operators of the Virasoro algebra and generalize it to higher order differential operators. Particular cases corresponding to quantum algebras existing in the literature are deduced. [ABSTRACT FROM AUTHOR]

KINEMATICS ,LIE algebras ,SPACE-time symmetries ,IDEALS (Algebra) ,ALGEBRA - Abstract
In a seminal paper, Bacry and Lévy–Leblond classified kinematical algebras, a class of Lie algebras encoding the symmetries of spacetime. Homogeneous spacetimes (infinitesimally, Klein pairs) associated with these possible kinematics can be partitioned into four families—riemannian, lorentzian, galilean, and carrollian—based on the type of invariant metric structure they admit. In this work, we classify possible ambient kinematics—defined as extensions of kinematical algebras by a scalar ideal—as well as their associated Klein pairs. Kinematical Klein pairs arising as quotient space along the extra scalar ideal are said to admit a lift into the corresponding ambient Klein pair. While all non-galilean Klein pairs admit a unique—trivial and torsionfree—higher-dimensional lift, galilean Klein pairs are constructively shown to admit lifts into two distinct families of ambient Klein pairs. The first family includes the bargmann algebra as well as its curved/torsional avatars while the second family is novel and generically allows lifts into torsional ambient spaces. We further comment on the relation between these two families and the maximally symmetric family of leibnizian Klein pairs. [ABSTRACT FROM AUTHOR]

The physical as well as topological properties of the components are then analysed. Studying the different analogies indeed help to have a clear and compact visualisation of both fields and thus to understand the nature of their field mechanisms. The use of geometric algebra within mathematical physics, further envisages geometrical meaning as well as the physical interpretation of mathematical elements. [ABSTRACT FROM AUTHOR]

The Lie superalgebra p s l (2 | 2) is recognized as a quite special algebra. In mathematics, it has the vanishing Killing form and allows for the three-dimensional central extension. In physics, it shows up as the symmetry of the one-dimensional Hubbard model and the asymptotic S-matrix of the anti-de Sitter/conformal field theory (AdS/CFT) correspondence. In this paper, we present the Drinfeld realization of the Yangian algebra associated with the centrally extended Lie superalgebra p s l (2 | 2). Furthermore, we show that it possesses Hopf algebra structures, particularly the coproducts. The idea to prove the existence of manifest coproducts is as follows. First, we shall introduce them to Levendorskii's realization, a system of a finite truncation of Drinfeld generators. Second, we show that Levendorskii's realization is isomorphic to the Drinfeld realization by induction. [ABSTRACT FROM AUTHOR]

The paper contains a description of generating elements of algebras of block-symmetric polynomials on finite and infinite ℓ
p -sums of spaces ℂs , s ∈ ℕ. In the case of a finite sum and s > 1 there are no algebraic bases in these algebras and we propose explicit formulas for algebraic dependencies between generating elements. [ABSTRACT FROM AUTHOR]- Published

Homomorphic Encryption, a magic wand in the field of cryptography that enables the user to perform secure computation over encrypted data, without decrypting the data. It allows cloud service providers to have access to encrypted data instead of original data, which also facilitates secure computation over encrypted data along with the secure transmission of it. NTRU, open-source public-key cryptography, based on lattices, is one of the standards of Homomorphic Encryption, can be used for secure outsourcing, the transmission of data, and performing computation on encrypted data. NTRU scheme is not vulnerable to quantum computer-based attacks, unlike existing traditional cryptographic techniques. In this paper, NTRU, the homomorphic encryption scheme is reviewed. The different variants of NTRU are also explainedthrough a detailed literature studybased on ring structure.The analysis also has been done that may help researchers to have a clear understanding of NTRU and its different variants and to distinguish them easily. The availability of different types of fields, rings based on different structures, different algebra, etc. for implementation of NTRU opens a new way for researchers to explore them to achieve a more efficient NTRU scheme for real-life applications.

Long time ago, Yang [Phys. Rev. 72, 874 (1947)] proposed a model of noncommutative spacetime that generalized the Snyder model to a curved background. In this paper, we review his proposal and the generalizations that have been suggested during the years. In particular, we discuss the most general algebras that contain as subalgebras both de Sitter and Snyder algebras, preserving Lorentz invariance, and are generated by a two-parameter deformation of the canonical Heisenberg algebra. We also define their realizations on quantum phase space, giving explicit examples, both exact and in terms of a perturbative expansion in deformation parameters. [ABSTRACT FROM AUTHOR]

This paper presents the developed algorithms for a tool environment for the design of complex information systems based on automata models using the algebra of high-dimensional vectors. The paper raises the problem of the little knowledge of methods of coding complex systems in the format of automata based on the algebra of hyperdimensional vectors. Methods of formalized description of systems in the form of hyperdimensional vectors and description of algorithms for transformation of formalized description using the algebra of hyperdimensional vectors are introduced. The features, advantages and disadvantages of modeling automata models using hyperdimensional vectors are listed. [ABSTRACT FROM AUTHOR]

We study the effects of the branching o s p (1 | 2 n) ⊃ g l (n) on a particular class of simple infinite-dimensional o s p (1 | 2 n) -modules L(p) characterized by a positive integer p. In the first part (Sec. III), we use combinatorial methods, such as Young tableaux and Young subgroups, to construct a new basis for L(p) that respects this branching, and we express the basis elements explicitly in two distinct ways: first, as monomials of negative root vectors of g l (n) acting on certain g l (n) -highest weight vectors in L(p) and then as polynomials in the generators of o s p (1 | 2 n) acting on a o s p (1 | 2 n) -lowest weight vector in L(p). In the second part (Sec. IV), we use extremal projectors and the theory of Mickelsson–Zhelobenko algebras to give new explicit constructions of raising and lowering operators related to the branching o s p (1 | 2 n) ⊃ g l (n). We use the raising operators to give new expressions for the elements of the Gel'fand–Zetlin basis for L(p) as monomials of operators from U (o s p (1 | 2 n)) acting on a o s p (1 | 2 n) -lowest weight vector in L(p). We observe that the Gel'fand–Zetlin basis for L(p) is related to the basis constructed earlier in this paper by a triangular transition matrix. We end this paper (Sec. V) with a detailed example treating the case n = 3. [ABSTRACT FROM AUTHOR]

As the loop space of a Riemannian manifold is infinite-dimensional, it is a non-trivial problem to make sense of the "top degree component" of a differential form on it. In this paper, we show that a formula from finite dimensions generalizes to assign a sensible "top degree component" to certain composite forms, obtained by wedging with the exponential (in the exterior algebra) of the canonical presymplectic 2-form on the loop space. This construction is a crucial ingredient for the definition of the supersymmetric path integral on the loop space. [ABSTRACT FROM AUTHOR]

COMMUTATION (Electricity) ,ALGEBRA ,GROBNER bases ,QUADRATIC equations ,COMMUTATORS (Operator theory) - Abstract
In recent years, various nonlinear algebraic structures have been obtained in the context of quantum systems as symmetry algebras, Painlevé transcendent models, and missing label problems. In this paper, we treat all these algebras as instances of the class of quadratic (and higher degree) commutator bracket algebras of Poincaré–Birkhoff–Witt type. We provide a general approach for simplifying the constraints arising from the diamond lemma and apply this in particular to give a comprehensive analysis of the quadratic case. We present new examples of quadratic algebras, which admit a cubic Casimir invariant. The connection with other approaches, such as Gröbner bases, is developed, and we suggest how our explicit and computational techniques can be relevant in other contexts. [ABSTRACT FROM AUTHOR]

ALGEBRA ,LOGICAL prediction - Abstract
It was conjectured by Belavin et al. [J. High Energy Phys. 2013(3), 35] that bosonization of a singular vector (in the Neveu–Schwarz sector) of the N = 1 super analog of the Virasoro algebra can be identified with the Uglov symmetric function. In this paper, we prove this conjecture. We also extend this result to the Ramond sector of the N = 1 super-Virasoro algebra. [ABSTRACT FROM AUTHOR]

ALGEBRA - Abstract
In this paper, we study non-weight modules over the super-Galilean conformal algebra. We construct and classify U (H) -free modules of rank 1 over the Ramond-type algebra and U (h) -free modules of rank 2 over the Neveu–Schwarz-type algebra, where H is a subalgebra of the Ramond-type algebra and h is the Cartan algebra of the Neveu–Schwarz-type algebra. We find that these modules are reducible and isomorphic. [ABSTRACT FROM AUTHOR]

The main aim of this work is to give some insights on various aspects of lower dimensional gravity via constructing the consistent cross-couplings that can be introduced in D = 2 spacetimes between a collection of BF models and a set of arbitrary matter fields. We work in a standard QFT ansatz related to space-time locality and other a priori requests on the interaction vertices and perform various cohomological computations based on the local BRST cohomology of the free model. These results are further translated at the level of the overall functional that governs the interacting BF-matter models, known as the deformed solution to the master equation, from which we deduce all the properties and features of the allowed couplings and their underlying gauge algebra.
