Preconditioning Indefinite Discretization Matrices.
, 1987 The finite element discretization of many elliptic boundary value problems leads to linear systems with positive definite and symmetric coefficient matrices. Many efficient preconditioners are known for these systems.

In this paper, we investigate an elliptic boundary value problem involving a nonlinear logarithmic Robin boundary condition. The problem is formulated on a smooth bounded domain of $\R^2$ with mixed Dirichlet--Neumann--Robin boundary conditions.

, 2003 In this paper, we examine some computational issues on finite element discretization of the p-Laplacian. We introduced a class of descent methods with multi-grid finite element preconditioners, and carried out convergence analysis.

Nonconforming Mixed Discretization Of Second Order Elliptic Problems
, 2007 This paper seeks to extend these ideas to the mixed formulation of second order boundary value problems. A "patch--test" is designed as a powerful tool for probing the viability of nonconforming approximations.
