On monotone nonexpansive mappings in CATp(0) spaces
  • Research Summary
    • In this paper, based on some geometrical properties of CATp(0) spaces, for p≥2, we obtain two fixed point results for monotone multivalued nonexpansive mappings and proximally monotone nonexpansive mappings. Which under some assumptions, reduce to coincide and generalize a fixed point result for monotone nonexpansive mappings. This work is a continuity of the previous work of Ran and Reurings, Nieto and Rodríguez-López done for monotone contraction mappings.

The extended tanh method for solving systems of nonlinear wave equations
  • Research Summary
    • The extended tanh method with a computerized symbolic computation is used for constructing the traveling wave solutions of coupled nonlinear equations arising in physics. The obtained solutions include solitons, kinks and plane periodic solutions. The applied method will be used to solve the generalized coupled Hirota Satsuma KdV equation.

Soliton Solutions of the Kaup-Kupershmidt and Sawada-Kotera Equations
  • Research Summary
    • In this paper I seek soliton solutions of two-component generalizations of the Kaup-Kupershmidt and Sawada-Kotera equations, for this purpose I will apply the extended tanh method. The extended tanh method with a computerized symbolic computation, is used for constructing the travelling wave solutions of coupled nonlinear equations arising in physics. The obtained solutions include soliton, kink and plane periodic solutions. KeyWords: Soliton Solutions; Kaup-Kupershmidt Equation; Sawada-Kotera Equation

Best proximity points in partially ordered metric spaces
  • Research Summary
    • The existence of best proximity point is an important aspect of optimization theory. We define the concept of proximally monotone Lipschitzian mappings on a partially ordered metric space. Then we obtain sufficient conditions for the existence and uniqueness of best proximity points for these mappings in partially ordered CAT (0) spaces. This work is a continuation of the work of Ran and Reurings [Proc. Amer. Math. Soc. 132 (2004), 1435–1443] and Nieto and Rodr ıguez-López [Order, 22 (2005), 223–239] for the new class of mappings introduced herein.

Existence and convergence of best proximity points in CATp(0) spaces
  • Research Summary
    • In this work, we study existence and convergence of best proximity points of a cyclic contraction mapping in a complete CATp(0) metric space, with p≥2. The case of coupled best proximity points of a pair of cyclic contraction mappings is also discussed. As an application, we provide sufficient conditions to obtain an extension of the Banach Contraction Principle for coupled fixed points.

    • We extend the Gromov geometric definition of CAT (0) spaces to the case where the comparison triangles are not in the Euclidean plane but belong to a general Banach space. In particular, we study the case where the Banach space is , for .

Viscosity approximation method for generalized asymptotically quasi-nonexpansive mappings in a convex metric space
  • Research Summary
    • A general viscosity iterative method for a finite family of generalized asymptotically quasi-nonexpansive mappings in a convex metric space is introduced. Special cases of the new iterative method are the viscosity iterative method of Chang et al. (Appl. Math. Comput. 212:51-59, 2009), an analogue of the viscosity iterative method of Fukhar-ud-din et al. (J. Nonlinear Convex Anal. 16:47-58, 2015) and an extension of the multistep iterative method of Yildirim and Özdemir (Arab. J. Sci. Eng. 36:393-403, 2011). Our results generalize and extend the corresponding known results in uniformly convex Banach spaces and spaces simultaneously.

Browder and Göhde fixed point theorem for G-nonexpansive mappings
  • Research Summary
    • In this paper, we prove the analog to Browder and Göhde fixed point theorem for G-nonexpansive mappings in complete hyperbolic metric spaces uniformly convex. In the linear case, this result is refined. Indeed, we prove that if X is a Banach space uniformly convex in every direction endowed with a graph G, then every G-nonexpansive mapping T: A→ A, where A is a nonempty weakly compact convex subset of X, has a fixed point provided that there exists u0∈ A such that T (u0) and u0 are G-connected. c 2016 All rights reserved.

PhD Thesis Topic : Functional Analysis and Metric Geometry Title : Fixed Point Theory of  Nonexpansive Mappings in Hyperbolic  Spaces   Supervisors : Professor A. R. Khan & Professor M. A. Khamsi Abstract : In this thesis, we establish analogues of classical theory of nonexpansive mappings in  hyperbolic spaces. Some fundamental fixed point results in partially ordered Banach  spaces are extended to hyperbolic spaces. A new characterization of reflexive and  strictly convex Banach spaces is established. We also discuss this characterization  in hyperbolic spaces. An extension of the Banach Contraction Principle for best  proximity points in CAT(0) spaces is obtained. Moreover, the case of nonexpansive  mappings is also discussed in this setting. An extension of the Gromov geometric  definition of CAT(0) spaces is introduced. Finally, iterative approximation of  common fixed points of nonexpansive and quasi-nonexpansive mappings defined on  convex metric spaces is studied
