Abstract

So far, the numerous methods for solving and analyzing differential equations are proposed. Meanwhile; the combined methods are beneficial; one of them is the Optimized MRA method (OMRA). This method is based on the Father wavelets (dependent on the invariant solutions obtained by the Lie symmetry method) and correspondent MRA. In this paper, we apply the OMRA on the generalized version of FKPP equation (GFKPP) with function coefficient
futt(x,t) + ut(x,t) = uxx(x,t) + u(x,t) - u2(x,t),
where f is a smooth function of either x or t.
We will see that by the suitable Father wavelets, this method proposes attractive approximate solutions.
