Numerical study of Fisher's equation by wavelet Galerkin method
Ramesh Chand Mittal, Sumit Kumar · International Journal of Computer Mathematics · 2006
Fisher's equation, which describes the logistic growth–diffusion process and occurs in many biological and chemical processes, has been studied numerically by the wavelet Galerkin method. Wavelets are functions which can provide local finer details. The solution of Fisher's equation has a compact support property and therefore Daubechies' compactly supported wavelet basis has been used in this study. The results obtained by the present method are highly encouraging and can be computed for a large value of the linear growth rate.
