The need to evaluate expressions of the form f (A)v, where A is a large sparse or structured symmetric matrix, v is a vector, and f is a nonlinear function, arises in many applications. The extended Krylov subspace method can be an attractive scheme for computing approximations of such expressions.

Discretization of the Stokes equations produces a symmetric indefinite system of linear equations. For stable discretizatiom a variety of numerical methods have been proposed that have rates of convergence independent of the mesh size used in the dkretization. In this paper we compare the performanc
It is known that the convergence behavior of Galerkin-Krylov subspace methods for solving linear systems can be very erratic. A smoothing technique or a minimal residual seminorm variant of these Galerkin methods can be proposed to eliminate this problem. In this paper we examine a class of minimal
