Abstract: Epi/hypo convergence is extended to the case of finite-valued bifunctions defined
on nonrectangular domains. Its basic characterizations are established. Variational properties such as those about saddle points, weak saddle points, minsup points, sup-projection, etc, of bifunctions are shown to be preserved for their epi/hypo limits (possibly under some additional assumptions). Applications to quasi equilibrium problems and multiobjective quasi optimization together with their dual problems are provided. The obtained results are new, some are significantly different from the counterparts for the rectangular case and some improve known results, when applied to this special case.
