GENERALIZED FIXED POINT THEOREM
Let X be a metric space, A be a nonempty closed convex subset of a uniformly convex Banach space \((Y,| \cdot |)\), \(CB(A)\) be the collection of all nonempty closed convex and bounded subsets of A metrized by the Hausdorff metric D. the following Krasnosielskii type fixed point theorem is proved: Suppose that \(\Gamma: A\to X\) is a continuous ...

Some fixed-point theorems of convex orbital $(\alpha, \beta )$-contraction mappings in geodesic spaces [PDF]
The aim of this paper is to broaden the applicability of convex orbital ( α , β ) $(\alpha, \beta )$ -contraction mappings to geodesic spaces. This class of mappings is a natural extension of iterated contraction mappings.

Measures of noncompactness in modular spaces and fixed point theorems for multivalued nonexpansive mappings [PDF]
This paper is devoted to state some fixed point results for multivalued mappings in modular vector spaces. For this purpose, we study the uniform noncompact convexity, a geometric property for modular spaces which is similar to nearly uniform convexity ...

Some Remarks on Multidimensional Fixed Point Theorems
MARTINEZ-MORENO, JUAN/0000-0002-3340-2781In this paper, we show that most of the multidimensional (including coupled, tripled, quadrupled) fixed point theorems in the context of (ordered) metric spaces are, in fact, immediate consequences of well-known ...

A Noncontractive Fixed Point Theorem [PDF]
The sequence Txn so constructed contains a subsequence TXnk which converges to some x X and which, by Ascoli's theorem [3], is equicontinuous. It follows in turn from (1) that the sequence Xnk is equicontinuous. To complete the proof it suffices to show xn,(t)-x(t) in B.

Fixed Point Theorems via α-ϱ-Fuzzy Contraction
Some well known results from the existing literature are extended and generalized via new contractive type mappings in fuzzy metric spaces. A non trivial supporting example is also provided to demonstrate the validity of the obtained results.

Approximate fixed point theorems [PDF]
The authors discuss weakenings of the conditions in the fixed point theorems of Brouwer, Kakutani and Banach which still guarantee the existence of approximate fixed points.

A Suzuki Type Fixed‐Point Theorem [PDF]
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).

Some Common Fixed Point Theorems in Menger Spaces [PDF]
summary:In this paper, we prove some common fixed point theorems for occasionally weakly compatible mappings in Menger spaces. An example is also given to illustrate the main result. As applications to our results, we obtain the corresponding fixed point

Common fixed point theorems and applications
The purpose of this paper is to discuss the existence of common fixed points for mappings in general quasi-metric spaces. As applications, some common fixed point theorems for mappings in probabilistic quasi-metric spaces are given. The results presented
