A New Fixed Point Theorem and Applications

Abstract and Applied Analysis, 2013
A new fixed point theorem is established under the setting of a generalized finitely continuous topological space (GFC-space) without the convexity structure. As applications, a weak KKM theorem and a minimax inequalities of Ky Fan type are also obtained

On a fixed point theorem of Greguš

International Journal of Mathematics and Mathematical Sciences, 1986
We consider two selfmaps T and I of a closed convex subset C of a Banach space X which are weakly commuting in X, i.e.‖TIx−ITx‖≤‖Ix−Tx‖   for   any   x   in   X,and satisfy the inequality‖Tx−Ty‖≤a‖Ix−Iy‖+(1−a)max{‖Tx−Ix‖,‖Ty−Iy‖}for all x, y in C, where ...

Mizoguchi-Takahashi’s Fixed Point Theorem Concerning τ−Distance

Journal of Mathematical Extension, 2010
In this paper by using the notion of τ -distance, we will prove Mizoguchi-Takahashi’s fixed point theorem, which is a generalization of fixed point theorem which has been given by ...

Fixed Point Theorems for Manageable Contractions with Application to Integral Equations

Journal of Function Spaces, 2017
In this paper we utilize the concept of manageable functions to define multivalued α⁎-η⁎ manageable contractions and prove fixed point theorems for such contractions.

Nonlinear Inequality, Fixed Point and NashEquilibrium [PDF]

In this paper, we give new sufficient conditions for the existence of a solution of theg-maximum equality. As a consequence, we prove a new fixed point theorem.
