Some Existence Results for Solutions of Generalized Vector Quasi-equilibrium Problems

[[abstract]]In this paper, we consider more general forms of generalized vector quasi-equilibrium problems for multivaluedmaps which include many known vector quasi-equilibrium problems and generalized vector quasi-variational inequality problems as special cases. We establish some existence results for solutions of these problems under pseudomonotonicity and u-hemicontinuity/ -hemicontinuity assumptions
