The present paper is in two-fold. The first fold is devoted to the existence theory of equilibria for generalized abstract economy with
a lower semicontinuous constraint correspondence and a fuzzy constraint correspondence defined on a noncompact/nonparacompact
strategy set. In the second fold, we consider systems of generalized vector quasi-equilibrium problems for multivalued maps (for short,
SGVQEPs) which contain systems of vector quasi-equilibrium problems, systems of generalized mixed vector quasi-variational
inequalities and Debreu-type equilibrium problems for vector valued functions as special cases. By using the results of first fold,
we establish some existence results for solutions of SGVQEPs.
