Equilibria of noncompact generalized games with U-majorized preference correspondences

AbstractIn this paper, some existence theorems of equilibria for qualitative games and generalized games with an infinite number of agents with noncompact strategy sets and with U-majorized preference correspondences are proved. Our theorems improve some recent results in the literatures

Maximal element theorems in product FC-spaces and generalized games

AbstractLet I be a finite or infinite index set, X be a topological space and (Yi,{φNi})i∈I be a family of finitely continuous topological spaces (in short, FC-space). For each i∈I, let Ai:X→2Yi be a set-valued mapping. Some existence theorems of maximal elements for the family {Ai}i∈I are established under noncompact setting of FC-spaces. As applications, some equilibrium existence theorems for generalized games with fuzzy constraint correspondences are proved in noncompact FC-spaces. These theorems improve, unify and generalize many important results in recent literature

A new equilibrium existence theorem for abstract fuzzy economies

AbstractIn this paper, we show a new equilibrium existence theorem for abstract fuzzy economies with uncountable number of agents with fuzzy constraint correspondences and fuzzy preference correspondence, and give a new existence theorem of maximal element for qualitative fuzzy games with uncountable number of players with fuzzy preference correspondence
