Abstract: The goal of this paper is to introduce and investigate a model called the stochastic tensor variational inequality (denoted by STVI), which is a natural extension of the stochastic linear complementarity problem and the stochastic affine variational inequality. Firstly, the STVI is transformed into an expected residual minimization (ERM) problem involved the regularized gap function. Then, the properties of the ERM problem are investigated. Finally, a discrete approximation of ERM problem is obtained by quasi-Monte Carlo method. The convergence of optimal solutions and stationary points of the approximation problem are analyzed as well.
