ON THE NUMERICAL SOLUTION OF GENERALIZED KPP EQUATION
关于广义KPP方程的数值解

The generalized KPP(Kolmogorov-Petrovskii-Piskunov) equation is an integro-differential equation.To investigate numerical solution for this problem,we first change the integro-differential equation to a form of nonlinear hyperbolic equation.Then a difference scheme is constructed to approximate initial boundary-value problem of hyperbolic equation. Existence and uniqueness are obtained for the difference scheme.Convergence and unconditional stability with respect to initial value are also discussed by using...
