On the existence of maximal elements, fixed points and equilibria of generalized games in a fuzzy environment

摘要

We give new sufficient conditions for the existence of fuzzy maximal elements, fuzzy fixed points and equilibria of generalized fuzzy games. In our results, a key role is played by the existence of upper semicontinuous selection maps of set-valued functions, that we obtain for the class of generalized transfer open lower sections maps.
