Nonlinear Inequality, Fixed Point and NashEquilibrium [PDF]

In this paper, we give new sufficient conditions for the existence of a solution of theg-maximum equality. As a consequence, we prove a new fixed point theorem.

Fixed point theorems for set-valued contraction type maps in metric spaces

, 2010
We first give some fixed point results for set-valued self-map contractions in complete metric spaces. Then we derive a fixed point theorem for nonself set-valued contractions which are metrically inward. Our results generalize many well-known results in

Solvability of integral equations via the technique of measures of noncompactness

Miskolc Mathematical Notes
Motivated by the work of [Mohammadi et al., Mathematics, 2019, 7, 575.], we extend here Darbo’s fixed point theorem in a Banach space using the combined technique of Wardowski-Mizoguchi-Takahashi contraction.

Borsuk's antipodal and fixed-point theorems for correspondences without convex values [PDF]

We present an extension of Borsuk's antipodal theorem (existence of a zero) for antipodally approachable correspondences without convex values. This result is a generalization of Borsuk-Ulam Theorem and has a fixed-point equivalent formulation.Borsuk's ...

RAKOTCH TYPE EXTENSION OF DARBO’S FIXED POINT THEOREM AND AN APPLICATION

In this paper, we present a new extension of Darbo’s fixed point theorem inspired by Rakotch’s contraction. We also provide the alternative version of Leray-Schauder type of our new result.

New Results on Fixed Points and Coupled Fixed Points for α-Admissible Condensing Operators

Axioms
This paper introduces a novel class of condensing mappings through the concept of α-admissibility. We prove several extensions of Darbo’s fixed point theorem within this framework, including a generalized contractive condition and a coupled fixed point ...

New Caputo fractional differential equation of higher order on unbounded interval and solvability in the Hölder space C 0 , q ( Ω ) $C^{0,q}(\Omega )$

Journal of Inequalities and Applications
We define a new Caputo fractional differential equation of higher-order on unbounded interval { D α c w ( t ) = f ( t ) , 0 ≤ t < ∞ , w ( 0 ) = w ′ ( 0 ) = w ( 4 ) ( 0 ) = w ( 5 ) ( 0 ) = ⋯ = w ( n ) ( 0 ) = 0 , w ‴ ( 0 ) = ∫ 0 η ( η − s ) α − 1 Γ ( α ...
