3. Coupled Best Proximity Points for Cyclic Kannan and Chatterjea Contractions in CATp(0) Spaces.

Author

MONGKOLKEHA, CHIRASAK, DECHBOON, PREMYUDA, SALISU, SANI, and KHAMMAHAWONG, KONRAWUT

Abstract

This paper considers the framework of CATp(0) spaces and analyzes coupled best proximity points for cyclic Kannan and cyclic Chatterjea contractions. The framework is substantial and versatile for employing metric notions and contractive conditions. For each mapping, we establish the existence and uniqueness of the coupled best proximity point. The work gives a step toward investigating the best proximity points in CATp(0) spaces. [ABSTRACT FROM AUTHOR]

Abstract

The purpose of this article is to prove some fixed point theorems for simulation functions in complete b-metric spaces with partially ordered by using wt-distance which introduced by Hussain et al. [12]. Also, we give some examples to illustrate our main results. [ABSTRACT FROM AUTHOR]

45. Optimal Approximate Solution for $$\alpha $$ α -Multiplicative Proximal Contraction Mappings in Multiplicative Metric Spaces

Author

Mongkolkeha, Chirasak and Sintunavarat, Wutiphol

Abstract

In this work, we introduce the new concept of $$\alpha $$ α -multiplicative proximal contraction mappings in the setting of multiplicative metric spaces and we also solve optimal approximate solution for such mappings. Our main results improve and extend several results in the literature. We also state some illustrative examples to claim that our results properly generalizes some results in literature.

46. Fixed Point Theorems for Generalized α-β-Weakly Contraction Mappings in Metric Spaces and Applications.

Author

Latif, Abdul, Mongkolkeha, Chirasak, and Sintunavarat, Wutiphol

Subjects
FIXED point theory, MATHEMATICAL mappings, METRIC spaces, MATHEMATICAL logic, BINARY number system, MATHEMATICAL analysis
Abstract

We extend the notion of generalized weakly contraction mappings due to Choudhury et al. (2011) to generalized α-β-weakly contraction mappings. We show with examples that our new class of mappings is a real generalization of several known classes of mappings. We also establish fixed point results for such mappings in metric spaces. Applying our new results, we obtain fixed point results on ordinary metric spaces, metric spaces endowed with an arbitrary binary relation, and metric spaces endowed with graph.

48. Some Common Fixed Point Theorems for Generalized F-Contraction Involving w-Distance with Some Applications to Differential Equations.

Author

Mongkolkeha, Chirasak and Gopal, Dhananjay

Subjects
*FIXED point theory, *CONTRACTION operators, *DIFFERENTIAL equations, *METRIC spaces, *THEORY of distributions (Functional analysis)
Abstract

In this paper, we introduce the Ćirić type generalized F-contraction and establish certain common fixed point results for such F-contraction in metric spaces with the w-distances. In addition, we give some examples to support our results. Finally, we apply our results to show the existence of solutions of the second order differential equation. [ABSTRACT FROM AUTHOR]
