We generalize the F-K invariant, i.e. (Z) over cap for the complement of a knot Kin the 3-sphere, the knots-quivers correspondence, and A-polynomials of knots, and find several interconnections between them. We associate an F-K invariant to any branch of the A-polynomial of K and we work out explicit expressions for several simple knots. We show that these F-K invariants can be written in the form of a quiver generating series, in analogy with the knots-quivers correspondence. We discuss various methods to obtain such quiver representations, among others using R-matrices. We generalize the quantum a-deformed A-polynomial to an ideal that contains the recursion relation in the group rank, i.e. in the parameter a, and describe its classical limit in terms of the Coulomb branch of a 3d-5d theory. We also provide t-deformed versions. Furthermore, we study how the quiver formulation for closed 3-manifolds obtained by surgery leads to the superpotential of 3d N = 2 theory T[M-3] and to the data of the associated modular tensor category MTC[M-3].

Reducing a 6d fivebrane theory on a 3-manifold Y gives a q-series 3-manifold invariant (Z ) over cap (Y). We analyse the large-N behaviour of F-K = (Z ) over cap (M-K), where M-K is the complement of a knot K in the 3-sphere, and explore the relationship between an a-deformed (a = q(N)) version of F-K and HOMFLY-PT polynomials. On the one hand, in combination with counts of holomorphic annuli on knot complements, this gives an enumerative interpretation of F-K in terms of counts of open holomorphic curves. On the other, it leads to closed form expressions for a-deformed F-K for (2, 2p + 1) torus knots and an order-by-order construction for other cases. They both suggest a further -deformation based on superpolynomials, which can be used to obtain a 1-deformation of ADO polynomials, expected to be related to categorification. Moreover, studying how F-K transforms under natural geometric operations on K indicates relations to quantum modularity in a new setting.

A física teòrica, la Teoria Quàntica de Camps (TQC) és un marc teòric extremadament reeixit que combina la Relativitat Especial amb la Mecànica Quàntica, permetent el diseny de models físics de les partícules subatómiques i quasipartícules que descriuen els aspectes més fundamentals de la matèria amb una precisió increïblement alta. Entre aquestes teories, la TQC Chern-Simons és una especial, que no només descriu fenòmens topològics a la física com ara l’Efecte Hall Quàntic, sinó que encaixa amb la noció del que es coneix com una Teoria Topològica de Camps Quàntics (TTCQ). Va ser fent servir aquests axiomes de les TTCQs que Edward Witten va mostrar al 1989 com d’estretament relacionada està la teoria de Chern-Simons amb l’àmbit d’invariants polinòmics que apareixen a la Teoria de Nusos, com ara el ben conegut polinomi de Jones. En aquests darrers anys, investigacions en aquest camp han donat lloc a nous i més poderosos invariants d’enllaços i, a través de cirurgies de Dehn sobre ells, de 3-varietats també. Per exemple, la sèrie de Gukov-Manolescu recentment proposta el 2020 —denotada FK(x, q)— és un invariant conjectural de complements de nusos que, en cert sentit, continua analíticament els polinomis de Jones colorejats. Poc després, Sunghyuk Park va introduir l’enfoc de la Matriu R de Gran Color corresponent a sl(2,C) per estudiar FK per trenats positius i calcular FK per a diversos nusos i enllaços. Aquest procediment ha estat així mateix extès per Angus Gruen a totes les altres àlgebres de Lie sl(n+1) més enllà de sl(2). En aquest treball, després d’un extens repàs sobre els anteriorment esmentats conceptes, abordem la família so(2n) d’àlgebres de Lie semisimples sobre els complexos a la classificació de Cartan, centrant-nos principalment en el cas so(8) atrets per la simetria triple al seu diagrama de Dynkin D4., En física teórica, la Teoría Cuántica de Campos (TCC) es un marco teórico extremadamente exitoso que combina la Relatividad Especial con la Mecánica Cuántica, permitiendo el diseño de modelos físicos de las partículas subatómicas y cuasipartículas que describen los aspectos más fundamentales de la materia con una precisión increíblemente alta. Entre dichas teorías, la TCC Chern-Simons es una especial, que no sólo describe fenómenos topológicos en física tales como el Efecto Hall Cuántico, sino que encaja con la noción de lo que se conoce como una Teoría Topológica de Campos Cuánticos (TTCC). Fue utilizando estos axiomas de las TTCCs que Edward Witten mostró en 1989 cómo de estrechamente relacionada está la teoría de Chern-Simons con el ámbito de invariantes polinómicos que aparecen en la Teoría de Nudos, tales como el bien conocido polinomio de Jones. En estos últimos años, investigaciones en este campo han dado lugar a nuevos y más poderosos invariantes de enlaces y, a través de cirugías de Dehn sobre ellos, así mismo de 3-variedades. Por ejemplo, la serie de Gukov-Manolescu recientemente propuesta en 2020 —denotada FK(x, q)— es un invariante conjetural de complementos de nudos que, en cierto sentido, continúa analíticamente los polinomios de Jones coloreados. Poco después, Sunghyuk Park introdujo el enfoque de la Matriz R de Gran Color correspondiente a sl(2,C) para estudiar FK para trenzados positivos y calcular FK para varios nudos y enlaces. Este procedimiento ha sido a su vez extendido por Angus Gruen a todas las otras álgebras de Lie sl(n+1) más allá de sl(2). En la presente obra, tras un extenso repaso sobre los anteriormente mencionados conceptos, abordamos la família so(2n) de álgebras de Lie semisimples sobre los complejos en la clasificación de Cartan, centrándonos principalmente en el caso so(8) atraídos por la simetría triple en su diagrama de Dynkin D4., In theoretical physics, Quantum Field Theory (QFT) is an extremely successful theoretical framework combining both Special Relativity and Quantum Mechanics, enabling to design physical models of subatomic particles and quasiparticles describing the most fundamental aspects of matter with an incredibly high accuracy. Among these theories, the Chern-Simons QFT is a special one, not only describing topological phenomena in physics such as the Quantum Hall Effect, but also fitting the notion of what is known as a Topological Quantum Field Theory (TQFT). It was by using the axioms of TQFTs that Edward Witten showed back in 1989 how closely related the Chern-Simons theory is to the realm of polynomial invariants appearing in Knot Theory, such as the well-known Jones polynomial. In the past years, further research in this field has led to new and more powerful invariants of links and, by means of Dehn surgeries on them, of 3-manifolds as well. For instance, the Gukov-Manolescu series proposed recently in 2020 —denoted FK(x, q)— is a conjectural invariant of knot complements that, in a sense, analytically continues the colored Jones polynomials. Shortly after, Sunghyuk Park introduced the Large Color R-matrix approach for sl(2,C) to study FK for some simple links, giving a definition of FK for positive braid knots and computing FK for various knots and links. This procedure has in turn been extended by Angus Gruen to all other Lie algebras sl(n+1) beyond sl(2). In this work, after a broad review on the above mentioned background, we move on to the family so(2n) of complex semisimple Lie algebras in Cartan’s classification, mainly focusing on the so(8) case attracted by the three-fold symmetry in its Dynkin diagram D4., Outgoing

We propose and in some cases prove a precise relation between 3-manifold invariants associated with quantum groups at roots of unity and at generic $q$. Both types of invariants are labeled by extra data which plays an important role in the proposed relation. Bridging the two sides -- which until recently were developed independently, using very different methods -- opens many new avenues. In one direction, it allows to study (and perhaps even to formulate) $q$-series invariants labeled by spin$^c$ structures in terms of non-semisimple invariants. In the opposite direction, it offers new insights and perspectives on various elements of non-semisimple TQFT's, bringing the latter into one unifying framework with other invariants of knots and 3-manifolds that recently found realization in quantum field theory and in string theory., Comment: 75 pages, 4 figures; v2: misprints corrected

We build a connection between topology of smooth 4-manifolds and the theory of topological modular forms by considering topologically twisted compactification of 6d (1,0) theories on 4-manifolds with flavor symmetry backgrounds. The effective 2d theory has (0,1) supersymmetry and, possibly, a residual flavor symmetry. The equivariant topological Witten genus of this 2d theory then produces a new invariant of the 4-manifold equipped with a principle bundle, valued in the ring of equivariant weakly holomorphic (topological) modular forms. We describe basic properties of this map and present a few simple examples. As a byproduct, we obtain some new results on 't Hooft anomalies of 6d (1,0) theories and a better understanding of the relation between 2d (0,1) theories and TMF spectra., Comment: 74 pages

We construct a new class of three-dimensional topological quantum field theories (3d TQFTs) by considering generalized Argyres-Douglas theories on $S^1 \times M_3$ with a non-trivial holonomy of a discrete global symmetry along the $S^1$. For the minimal choice of the holonomy, the resulting 3d TQFTs are non-unitary and semisimple, thus distinguishing themselves from theories of Chern-Simons and Rozansky-Witten types respectively. Changing the holonomy performs a Galois transformation on the TQFT, which can sometimes give rise to more familiar unitary theories such as the $(G_2)_1$ and $(F_4)_1$ Chern-Simons theories. Our construction is based on an intriguing relation between topologically twisted partition functions, wild Hitchin characters, and chiral algebras which, when combined together, relate Coulomb branch and Higgs branch data of the same 4d $\mathcal{N}=2$ theory. We test our proposal by applying localization techniques to the conjectural $\mathcal{N}=1$ UV Lagrangian descriptions of the $(A_1,A_2)$, $(A_1,A_3)$ and $(A_1,D_3)$ theories., Comment: 6 pages

We find and propose an explanation for a large variety of modularity-related symmetries in problems of 3-manifold topology and physics of 3d $\mathcal{N}=2$ theories where such structures a priori are not manifest. These modular structures include: mock modular forms, $SL(2,\mathbb{Z})$ Weil representations, quantum modular forms, non-semisimple modular tensor categories, and chiral algebras of logarithmic CFTs., Comment: 119 pages, 10 figures and 20 tables

We take a peek at a general program that associates vertex (or, chiral) algebras to smooth 4-manifolds in such a way that operations on algebras mirror gluing operations on 4-manifolds and, furthermore, equivalent constructions of 4-manifolds give rise to equivalences (dualities) of the corresponding algebras., Comment: 40 pp, a new figure, many improvements and references added
