Generalized Equilibrium Problems

Mathematics, 2023
If X is a convex subset of a topological vector space and f is a real bifunction defined on X×X, the problem of finding a point x0∈X such that f(x0,y)≥0 for all y∈X, is called an equilibrium problem.

Inequality Problems of Equilibrium Problems with Application [PDF]

Sahand Communications in Mathematical Analysis, 2018
This paper aims at establishing the existence of results for a nonstandard equilibrium problems $(EP_{N})$. The solutions of this inequality are discussed in a subset $K$ (either bounded or unbounded) of a Banach spaces $X$. Moreover, we enhance the main

Solving the Set Equilibrium Problems [PDF]

Fixed Point Theory and Applications, 2011
We study the weak solutions and strong solutions of set equilibrium problems in real Hausdorff topological vector space settings. Several new results of existence for the weak solutions and strong solutions of set equilibrium problems are derived.

A New Iterative Algorithm for Multivalued Nonexpansive Mappping and Equlibruim Problems with Applications [PDF]

Sahand Communications in Mathematical Analysis, 2020
In this paper, we introduce two iterative schemes by a modified Krasnoselskii-Mann algorithm for finding a common element of the set of solutions of equilibrium problems and the set of fixed points of multivalued nonexpansive mappings in Hilbert space ...

The Role of Different Afferent Systems in the Modulation of the Otolith-Ocular Reflex After Long-Term Space Flights

Frontiers in Physiology, 2022
BackgroundThe vestibular (otolith) function is highly suppressed during space flight (SF) and the study of these changes is very important for the safety of the space crew during SF missions.

Ocular counter-roll is less affected in experienced versus novice space crew after long-duration spaceflight

npj Microgravity, 2022
Otoliths are the primary gravity sensors of the vestibular system and are responsible for the ocular counter-roll (OCR). This compensatory eye torsion ensures gaze stabilization and is sensitive to a head roll with respect to gravity and the Gravito ...

Prolonged microgravity induces reversible and persistent changes on human cerebral connectivity

Communications Biology, 2023
rs-fMRI is used to investigate human brain connectivity changes induced by prolonged microgravity in cosmonauts before and after spaceflight, with both persistent and reversible location specific changes in connectivity being observed.

A Discrete Characterization of the Solvability of Equilibrium Problems and Its Application to Game Theory

Axioms, 2023
We state a characterization of the existence of equilibrium in terms of certain finite subsets under compactness and transfer upper semicontinuity conditions.

Densely Defined Equilibrium Problems [PDF]

Journal of Optimization Theory and Applications, 2015
In the present work we deal with set-valued equilibrium problems for which we provide sufficient conditions for the existence of a solution. The conditions that we consider are imposed not on the whole domain, but rather on a self segment-dense subset of it, a special type of dense subset.
