“…One of the most important problems for (VEP) is to investigate the properties of the solution set, such as existence and uniqueness [11-13, 25-27, 31], semicontinuity and sensitivity [1,7], well-posedness [2,22,[28][29][30]32] and connectedness [16,17,23]. Among many desirable properties of the solution set, the issue of the nonemptiness and boundedness of the solution set is interesting and important, as it can guarantee the convergence of some solution algorithms (see, e.g., [21,33,34]).…”
