CONVERGENCE ESTIMATES FOR SEMIDISCRETE APPROXIMATIONS OF NONSELFADJOINT PARABOLIC EQUATIONS.

Authors

Irena Lasiecka

Abstract

Semidiscrete Galerkin approximations of the second-order nonselfadjoint parabolic equations are considered. L//2-error estimates for L//2-initial conditions are derived by use of semigroup methods and of analyticity of the underlined semigroup. The scheme here presented can be also freely applied to nonconforming elements.
