Fixed Points, Maximal Elements and Equilibria of Generalized Games in Abstract Convex Spaces

Abstract

We firstly prove some new fixed point theorems for set-valued mappings in noncompact abstract convex space. Next, two existence theorems of maximal elements for class of ${𝒜}_{C,\theta }$ mapping and ${𝒜}_{C,\theta }$-majorized mapping are obtained. As in applications, we establish new equilibria existence theorems for qualitative games and generalized games. Our theorems improve and generalize the most known results in recent literature.
