Abstract: In this paper, we apply our new results on quasi-variational inequality problems in [5] to generalized quasi-equilibrium problems. Some sufficient conditions on theexistence of solutions are shown. In particular, we establish several results on the existence of solutions to fixed points of lower semi-continuous mappings without conditions on closedness of values. These generalize some well-known fixed point theorems obtained by previous authors as F. E. Browder and Ky Fan, X. Wu, L. J. Lin, and Z. T. Yu etc.
