A New Existence Result of Equilibria for Vector Equilibrium Problems
Issam Dali, Mohamed Bilal Moustaid · Numerical Functional Analysis and Optimization · 2023
In this paper, we deal with vector equilibrium problems. We prove the nonemptiness of the solution set for this type of problems in the sequential compactness case and in the absence of convexity and lower semicontinuity assumptions. Some examples are presented and an existence result for countable systems of vector equilibrium problems is stated.
