We also discuss the convergence and stability of a new perturbed Ishikawa iterative algorithm for solving a class of generalized random nonlinear implicit quasi-variational inequalities involving random single-valued mappings. The results presented in this paper improve and extend the earlier and recent results. Copyright 2006 Heng-You Lan.

Introduction Throughout this paper we suppose that R denotes the set of real numbers and Q A p is a complete Ơ-finite measure space. Let E be a separable real Hilbert space endowed with the norm II II and inner product let D be a nonempty subset of E and let CB E denote the family of all nonempty bounded closed subsets of E. We denote by E the class of Borel Ơ-fields in E. In this paper we will consider the following new general random implicit quasi-variational inequality with random multivalued mappings by using a new class of projection method find x Q D and u v J Q E such that g t x t e J t v t u t e T t x t v t e F t x t J t e S t x t and a t u t g t y - g t x t N t f t x t J t g t y - g t x t 0 for all t e Q and g t y e J t v t where g Q X D E f Q X E E and N Q X E X E E are measurable single-valued mappings T S Q X D CB E and F Q X D CB D are random multivalued mappings J Q X D P E is a .
