THE CONNECTEDNESS OF SOLUTION SETS FOR A QUASICONVEX OPTIMIZATION IN INFINITE DIMENSIONAL SPACES

One of the key questions of multiobjective optimization theory is to investigatethe connectedness of solution sets. In this paper, the concept of quasiconvex, stronglyquasiconvex and strictly quasiconvex mappings are introduced. Under the condition thatthe constraint set is compact and convex while the objective function is continuous andquasiconvex (strongly and strictly quasiconvex), we prove the connectedness results of weaklyefficient solution sets (efficient sets) to multiobjective optimization problems. Particularly,we prove that if the objective function is strongly quasiconvex, then the efficient solutionsets is pathwise connected.
