摘要
The purpose of this paper is to study the numerical simulation of the generalized Fisher-Kolmogorov-Petrovskii-Piskunov equation. After introducing a new variable, the integro-differential equation is transformed into an equivalent coupled system of first-order differential equations. A second-order accurate difference scheme is constructed for the new system of equations, which is proved to be local uncoupled by separation of variables. It is also proved that the scheme is uniquely solvable and second-order convergent in both time and space in L-2-norm. A numerical example is given to demonstrate the theoretical results.
