## Abstract We study different variants of the augmented Lagrangian (AL)βbased blockβtriangular preconditioner introduced by the first two authors in [__SIAM J. Sci. Comput.__ 2006; **28**: 2095β2113]. The preconditioners are used to accelerate the convergence of the Generalized Minimal Residual me
The conforming spectral element methods are applied to solve the linearized Navier-Stokes equations by the help of stabilization techniques like those applied for finite elements. The stability and convergence analysis is carried out and essential numerical results are presented demonstrating the hi
In this paper an explicit Lagrangian approach to advective and diffusive term treatment has been derived to improve the stability and to reduce the artificial diffusion of a finite difference scheme for convection-diffusion equations. This concept is then applied to discretize the convective and vis
