A restrictive Padé approximation for the solution of the generalized Fisher and Burger-Fisher equations

Solving generalized Fisher and Burger-Fisher equations by the finite difference technique yields difficult nonlinear system of equations. In this paper linearization and restrictive Padé approximation is considered. It yields more accurate and faster results. Also the stability analysis is discussed. Numerical results are treated. © 2003 Elsevier Inc. All rights reserved.
