摘要
We study the following generalized quasivariational inequality problem: given a closed convex set X in a normed space E with the dual E*, a multifunction Phi : Chi -> 2(E*) and a multifunction Gamma : X -> 2(X), find a point (x, z) epsilon X x E* such that x epsilon Gamma (x), z epsilon Phi(x), < z, x - y > <= 0, for all gamma epsilon Gamma (x). We prove some existence theorems in which Phi may be discontinuous, X may be unbounded, and Gamma is not assumed to be Hausdorff lower semicontinuous.
