The purpose of this paper is to introduce a class of new random completely generalized set-valued implicit quasi-variational inequalities, to construct new random iterative algorithms, and to give some existence theorems of random solutions for this class of random completely generalized set-valued implicit quasi-variational inequalities. We also prove the convergence of random iterative sequences generated by the algorithms. Our results extend and improve the earlier and recent results. 相似文献

In this paper we investigate generalized bi-quasi-variational inequalities in locally convex topological vector spaces. Motivated and inspired by the recent research work in this field,we establish several existence theorems of solutions for generalized bi-quasi-variational inequalities,which are the extension and improvements of the earlier and recent results obtained previously by many authors including Sun and Ding [18],Chang and Zhang [23] and Zhang [24]. 相似文献

In a recent paper, Domokos and Kolumbán introduced variational inequalities with operator solutions to provide a suitable
unified approach to several kinds of variational inequality and vector variational inequality in Banach spaces. Inspired by
their work, in this paper, we further develop the new scheme of vector variational inequalities with operator solutions from
the single-valued case into the multi-valued one. We prove the existence of solutions of generalized vector variational inequalities
with operator solutions and generalized quasi-vector variational inequalities with operator solutions. Some applications to
generalized vector variational inequalities and generalized quasi-vector variational inequalities in a normed space are also
provided. 相似文献

Generalized Vector Variational Inequalities 总被引:6,自引:0,他引:6
In this paper, we introduce a generalized vector variational inequality problem (GVVIP) which extends and unifies vector variational inequalities as well as classical variational inequalities in the literature. The concepts of generalized C-pseudomonotone and generalized hemicontinuous operators are introduced. Some existence results for GVVIP are obtained with the assumptions of generalized C-pseudomonotonicity and generalized hemicontinuity. These results appear to be new and interesting. New existence results of the classical variational inequality are also obtained. 相似文献
