In this paper, we establish some fixed point theorems for a family of multivalued maps under mild
conditions. By using our fixed point theorems, we derive some maximal element theorems for a
particular family of multivalued maps, namely the -condensing multivalued maps. As applications
of our results, we prove some general equilibrium existence theorems in the generalized abstract
