### Abstract

Let $$E$$ and $$F$$ be Hausdorff topological vector spaces over the field $$\Phi$$ , let $$\left\langle , \right\rangle :F \times E \to \Phi$$ be a bilinear functional, and let $$X$$ be a non-empty subset of $$E$$ . Given a set-valued map $$S:X \to 2^X$$ and two set-valued maps $$M,T:X \to 2^F$$ , the generalized bi-quasi-variational inequality (GBQVI) problem is to find a point $$\hat y \in X$$ and a point $$\hat w \in T(\hat y)$$ such that $$\hat y \in S(\hat y)$$ and $$\operatorname{Re} \left\langle {f - \hat w,\hat y - x} \right\rangle \leqslant 0$$ for all $$x \in S(\hat y)$$ and for all $$f \in M(\hat y)$$ or to find a point $$\hat y \in X,$$ a point $$\hat w \in T(\hat y)$$ and a point $$\hat f \in M(\hat y)$$ such that $$\hat y \in S(\hat y)$$ and $$\operatorname{Re} \left\langle {\hat f - \hat w,\hat y - x} \right\rangle \leqslant 0$$ for all $$x \in S(\hat y)$$ . The generalized bi-quasi-variational inequality was introduced first by Shih and Tan [8] in 1989. In this paper we shall obtain some existence theorems of generalized bi-quasi-variational inequalities as application of upper hemi-continuous operators [4] in locally convex topological vector spaces on compact sets.
