On asymptotic global stability of linear variational inequalities in Hilbert space based on Hausdorff convergence
摘要
This note is concerned with stability of linear variational inequalities (VIs) in Hilbert space. We prove an asymptotic global convergence result under appropriate conditions for perturbations of all data of a linear VI, that consists of a linear operator, a right hand side, and a convex constraint set. Here we employ Hausdorff set convergence to handle perturbations in arbitrary closed convex constraint sets what is a main novelty of the paper. To provide a simple illustration of our abstract stability theory we consider a VI of Volterra type with memory term and with unilateral constraints on some time interval and a box constrained variational problem involving Fourier series. We derive asymptotic global stability results for these variational problems.
