Some fixed point theorems for discontinuous mappings [PDF]

open access: yes
This paper provides a fixed point theorem à la Schauder, where the mappings considered are possibly discontinuous. Our main result generalizes and unifies several well-known results.Schauder fixed point theorem, Brouwer fixed point theorem, discontinuity.

A fixed point theorem for distributions

open access: yesStochastic Processes and their Applications, 1992
The author studies, in a systematic form, the contractive behavior of the map \(S\) of distributions to distributions \(S(F)\overset{\mathcal D}=\sum_ i T_ i X_ i+C\), \((C,T=(T_ 1,T_ 2,\dots))\), \(X_ i\) are independent random variables with distribution function \(F\). Further the author obtains the higher and exponential moments of the fixed point.

A New Fixed Point Theorem and Applications

open access: yesAbstract 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 Krasnoselskii-Shafer type

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2002
In this paper a variant of a fixed point theorem to Krasnoselskii-Schaefer type is proved and it is further applied to certain nonlinear integral equation of mixed type for proving the existence of the solution.

Fixed Point Theorem for Monotone Non-Expansive Mappings

open access: yesInternational Journal of Analysis and Applications, 2021
In this paper, we study the fixed point theorem for monotone nonexpansive mappings in the setting of a uniformly smooth and uniformly convex smooth Banach space.

Fixed point theorem utilizing operators and functionals

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2012
This paper presents a fixed point theorem utilizing operators and functionals in the spirit of the original Leggett-Williams fixed point theorem which is void of any invariance-like conditions.
