TL;DR: In this paper, the authors prove three approximate selection theorems and give an improved version of the Michael selection theorem for generalized games, as well as a fixed point theorem and equilibrium theorem.
TL;DR: In this article, the concept of a function h P of non-convexity of the set P of a normed space is introduced, where h P is the graph of some continuous function of one variable.
TL;DR: In this article, a continuous selection theorem for convex-valued multifunctions satisfying slightly weaker lower semicontinuity assumptions than those which are adopted in the famous Michael Theorem was given.
Abstract: We give a continuous selection theorem for convex-valued multifunctions satisfying slightly weaker lower semicontinuity assumptions than those which are adopted in the famous Michael Theorem [4] and in [1].
TL;DR: By arguments combining selection theory and fixed point theory, some qualitative results are obtained for quasi-equilibrium problems involving sub-lower semicontinuous set-valued mappings in the setting of real Banach spaces.
Abstract: This paper deals with quasi-equilibrium problems in the setting of real Banach spaces. By a fixed point theory approach, we obtain existence results under mild conditions of continuity, improving some previous results in this area. By a selection theory approach, we make use of the Michael selection theorem to overcome the separability of the Banach spaces and generalize some results obtained recently in the literature. Finally, we deal with the existence of approximate solutions for quasi-equilibrium problems, and by arguments combining selection theory and fixed point theory, we obtain some qualitative results for quasi-equilibrium problems involving sub-lower semicontinuous set-valued mappings.
