Applications of Fixed Point Theorems to Generalized Saddle Points of Bifunctions on Chain-Complete Posets
We apply the extensions of the Abian-Brown fixed point theorem for set-valued mappings on chain-complete posets to examine the existence of generalized and extended saddle points of bifunctions defined on posets. We also study the generalized and extended equilibrium problems and the solvability of...
