Various kinds of semicontinuity and the solution sets of parametric multivalued symmetric vector quasiequilibrium problems (Q934804)

The authors study various quasi-equilibrium problems involving set-valued maps in infinite dimensional spaces. They introduce some new kinds of continuity for set-valued maps and establish these properties for the solution sets, in particular Hausdorff upper and lower semicontinuity and continuity with respect to a partially ordering cone are also addressed.
