摘要
In this paper, the connectedness of solution sets for generalized vector equilibrium problems via free-disposal sets (GVEPVF) in complete metric space is discussed. Firstly, by virtue of Gerstewitz scalarization functions and oriented distance functions, a new scalarization function omega is constructed and some properties of it are given. Secondly, with the help of omega, the existence of solutions for scalarization problems (GVEPVF)(omega) and the relationship between the solution sets of (GVEPVF)(omega) and (GVEPVF) are obtained. Then, under some suitable assumptions, sufficient conditions of (path) connectedness of solution sets for (GVEPVF) are established. Finally, as an application, the connectedness results of E-efficient solution set for a class of vector programming problems are derived. The obtained results are new, and some examples are given to illustrate the main results.
