Stability in a class of variational methods
The purpose of this work is to investigate the stability property of some models which are currently used in image processing. Following L. Rudin, S.J. Osher and E. Fatemi, we decompose an image f ∈ L2(R2) as a sum u+ v where u belongs to BV(R2) and v belongs to L2(R2). The Banach space BV is aimed at modeling the objects contained in the given image. the optimal decomposition minimizes the ene...

Interior Methods For a Class of Elliptic Variational Inequalities
We consider the application of primal-dual interior methods to the optimization of systems arising in the finite-element discretization of a class of elliptic variational inequalities. These problems lead to very large (possibly non-convex) optimization problems with upper and lower bound constraints. When interior methods are applied to the discretized problem, the resulting linear systems hav...
متن کاملA Class of Projection Methods for General Variational Inequalities
In this paper, we consider and analyze a new class of projection methods for solving pseudomonotone general variational inequalities using the Wiener–Hopf equations technique. The modified methods converge for pseudomonotone operators. Our proof of convergence is very simple as compared with other methods. The proposed methods include several known methods as special cases. 2002 Elsevier Scie...
