Preconditioned GMRES methods for discretization equation of nonsymmetric and indefinite elliptic problem
The author proposes and carefully analyzes a class of preconditioners for GMRES method for the solution of linear systems arising from discretization of second-order nonsymmetric and indefinite elliptic problems by a finite element method. The paper does not include any numerical experiment.
