Regularization and iterative methods for monotone inverse variational inequalities

We consider the monotone inverse variational inequality: find \(x\in H\) such that $$\begin{aligned} f(x)\in \Omega , \quad \left\langle \tilde{f}-f(x),x\right\rangle \ge 0, \quad \forall \tilde{f}\in \Omega , \end{aligned}$$ where \(\Omega \) is a nonempty closed convex subset of a real Hilbert space \(H\) and \(f:H\rightarrow H\) is a monotone mapping. A general regularization method for monotone inverse variational inequalities is shown, where the regularizer is a Lipschitz continuous and strongly monotone mapping. Moreover, we also introduce an iterative method as discretization of the regularization method. We prove that both regularized solution and an iterative method converge strongly to a solution of the inverse variational inequality.
