Abstract: Let be a topological vector space and be a nonempty subset of . Let and be two maps. Then the generalized quasivariational inequality (GQVI) problem is to find a point and a point such that for all . We shall use Chowdhury and Tan's 1996 generalized version of Ky Fan's minimax inequality as a tool to obtain some general theorems on solutions of the GQVI on a paracompact set in a Hausdorff locally convex space where the setvalued operator is either strongly pseudomonotone or pseudomonotone and is upper semicontinuous from to the weaktopology on for each nonempty finite subset of .
