A Suzuki Type Fixed-Point Theorem

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2011
We present a fixed-point theorem for a single-valued map in a complete metric space using implicit relation, which is a generalization of several previously stated results including that of Suziki (2008).

Fixed Point Theorem of Ciric-Pata Type

open access: yesInternational Journal of Analysis and Applications, 2019
In this article, we proved a fixed point theorem of Ćirić-Pata type in metric space. This result extends several results in the existing literature. Moreover, an example is given in the support of our result.

A uniqueness theorem for fixed points [PDF]

open access: yesProceedings of the American Mathematical Society, 1980
In a recent paper, R. Kellogg [3] showed that if F : D ¯ → D ¯ F:\bar D \to \bar D is a completely continuous map of the closure of a bounded, convex, open set D in a real Banach space X, F

Homological selections and fixed-point theorems

open access: yes, 2016
A homological selection theorem for C-spaces, as well as, a finite-dimensional homological selection theorem is established. We apply the finite-dimensional homological selection theorem to obtain fixed-point theorems for usco homologically UV^n set ...

Note on KKM maps and applications

open access: yesFixed Point Theory and Applications, 2006
We apply the KKM technique to study fixed point theory, minimax inequality and coincidence theorem. Some new results on Fan-Browder fixed point theorem, Fan's minimax theorem and coincidence theorem are obtained.
