Random fixed point theorems under mild continuity assumptions [PDF]

, 2013
In this paper, we study the existence of the random fixed points under mild continuity assumptions. The main theorems consider the almost lower semicontinuous operators defined on Frechet spaces and also operators having properties weaker than lower ...

Some Fixed Point Theorems in Fuzzy n-Normed Spaces [PDF]

, 2010
The main purpose of this paper is to study the existence of a fixed points in fuzzy n-normed spaces. we proved our main results, a fixed point theorem for a self mapping and a common fixed point theorem for a pair of weakly compatible mappings on fuzzy n-

Generalized 𝜶-𝝍 Contractive Type Mappings and Related Fixed Point Theorems with Applications

Abstract and Applied Analysis, 2012
We establish fixed point theorems for a new class of contractive mappings. As consequences of our main results, we obtain fixed point theorems on metric spaces endowed with a partial order and fixed point theorems for cyclic contractive mappings. Various

Fixed point theorems for F-expanding mappings

Fixed Point Theory and Applications, 2017
Recently, Wardowski (Fixed Point Theory Appl. 2012:94, 2012) introduced a new concept of F-contraction and proved a fixed point theorem which generalizes the Banach contraction principle.

Generalized fixed point theorems on metric spaces [PDF]

Mathematica Moravica, 2022
In this paper, we establish some fixed point theorems for single valued and multi-valued mappings on a complete metric space. Suzuki's and some other fixed point theorems are generalized by taking a more general contractive condition for single valued ...

Fixed Point Theorems via α-ϱ-Fuzzy Contraction

Axioms, 2019
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.

Common fixed point theorems and applications

International Journal of Mathematics and Mathematical Sciences, 1997
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

Fixed-point-like theorems on subspaces

Fixed Point Theory and Applications, 2004
We prove a fixed-point-like theorem for multivalued mappings defined on the finite Cartesian product of Grassmannian manifolds and convex sets. Our result generalizes two different kinds of theorems: the fixed-point-like theorem by Hirsch et al.

Fixed point theorems for $alpha$-contractive mappings [PDF]

Sahand Communications in Mathematical Analysis, 2015
In this paper we prove existence the common fixed point with different conditions for $alpha-psi$-contractive mappings. And generalize weakly Zamfirescu map in to modified weakly Zamfirescu map.

GENERALIZED FIXED POINT THEOREMS IN G-CONE METRIC SPACES INVOLVING Φ-CONTRACTIONS AND AUXILIARY PERTURBATIONS [PDF]

Journal of Mechanics of Continua and Mathematical Sciences
In this work, we provide a set of enhanced fixed-point theorems over Banach spaces with normal cones in the context of G-cone metric spaces. Our results extend and generalize existing theorems by incorporating φ-contractive mappings and perturbation ...
