Asymptotic stability in the Schauder fixed point theorem [PDF]

open access: bronzeStudia Mathematica, 1998
Summary: This note presents a theorem which gives an answer to a conjecture which appears in the book ``Matrix norms and their applications'' by \textit{G. R. Belitskij} and \textit{Yu. I. Lyubich} (1988; Zbl 0645.15019) and concerns the global asymptotic stability in the Schauder fixed point theorem.

A Schauder fixed point theorem in semilinear spaces and applications [PDF]

open access: goldFixed Point Theory and Applications, 2013
Abstract In this paper we present existence and uniqueness results for a class of fuzzy fractional integral equations. To prove the existence result, we give a variant of the Schauder fixed point theorem in semilinear Banach spaces. MSC:34A07, 34A08.

A hybrid Krasnosel’skiĭ-Schauder fixed point theorem for systems

open access: hybridNonlinear Analysis: Real World Applications
We provide new results regarding the localization of the solutions of nonlinear operator systems. We make use of a combination of Krasnosel'ski\uı cone compression-expansion type methodologies and Schauder-type ones. In particular we establish a localization of the solution of the system within the product of a conical shell and of a closed convex set.

Existence and uniqueness of neutral functional differential equations with sequential fractional operators. [PDF]

open access: yesPLoS ONE
In this research paper, we investigate the existence and uniqueness of solutions for neutral functional differential equations with sequential fractional orders, specifically involving the [Formula: see text]-Caputo operator.

Some Generalizations of Mulit-Valued Version of Schauders Fixed Point Theorem with Applications [PDF]

open access: diamondCubo (Temuco), 2010
Let \(E\) be a Banach space and \(\mu \) an axiomatically defined measure of noncompactness in \(E\). The following theorem is the main result of this paper: Let \(X\) be a closed, convex and bounded subset of \(E\) and \(Q:X\to 2^X\) a multi-valued mapping with closed graph and convex values.

Generalizations of F. E. Browder's sharpened form of the schauder fixed point theorem [PDF]

open access: bronzeJournal of the Australian Mathematical Society. Series A. Pure Mathematics and Statistics, 1987
AbstractLet E be a Hausdorff topological vector space, let K be a nonempty compact convex subset of E and let f, g: K → 2E be upper semicontinuous such that for each x ∈ K, f(x) and g(x) are nonempty compact convex. Let Ω ⊂ 2E be convex and contain all sets of the form x − f(x), y − x + g(x) − f(x), for x, y ∈ K.

FIXED POINT THEOREMS FOR CONDENSING MAPPINGS SATISFYING LERAY-SCHAUDER TYPE CONDITIONS

open access: bronzeCommunications of the Korean Mathematical Society, 2016
In this paper, some new fixed point theorems for condensing mappings are established based on a well known result of Petryshyn. We use several Leray-Schauder type conditions to prove new fixed point re- sults. We also obtain generalizations of Altman's theorem and Petryshyn's theorem as well. 1.
