Abstract

This paper aims to provide new sufficient conditions for the existence of solutions to a vector quasi-equilibrium problem with set-valued mappings. Using a very recent Browder-type fixed-point theorem, which allows us to relax the common lower semicontinuity assumptions, the results improve some theorems from the literature and they can be applied where others fail.
