Linearly implicit time discretization of nonlinear parabolic equations. (English) Zbl 0834.65092
The authors consider linearly implicit one-step methods for time- discretization of linear and nonlinear parabolic differential equations. Stability results and several error estimates with different approximation orders are proven for the Rosenbrock methods and the $$W$$- methods where the last ones do not require the exact Jacobian of the problem. Remarks on the convergence order of the extrapolated linearly implicit Euler method are given.
The parabolic equations are studied in a Hilbert space framework. Several examples are considered, e.g., semilinear and quasilinear parabolic equations and stiff reaction-diffusion equations. The paper contains no numerical results.
