Approximation par des morphismes de chaînes et points fixes des applications multivoques [PDF]
, 2012 2010 Mathematics Subject Classification: 54C60, 54H25.In this paper, we consider u.s.c. multivalued maps with compact point images. We develop a notion of approximation of such maps by chain mappings between the singular chain complexes of the spaces ...

Coincidence theorems and minimax inequalities in abstract convex spaces [PDF]
, 2011 In this paper, we deal with the notion of abstract convex spaces via minimal spaces as an extended version of other forms of convexity and establish some well-known results such as coincidence theorems for the classes m-KKM and ms-KKM of multimaps and Ky

Generalization of fixed point theorems in ordered metric spaces concerning generalized distance
, 2011 In this article, we consider ordered metric spaces concerning generalized distance and prove some fixed point theorems in these spaces. Our results generalize, improve, and simplify the proof of the previous results given by some authors.

Convergence and stability of generalized φ-weak contraction mapping in CAT(0) spaces
Open Mathematics, 2017 The aim of this paper is to prove some fixed point results for generalized φ-weak contraction mapping and study a new concept of stability which is called comparably almost T-stable by using iterative schemes in CAT(0) spaces.
