High Order Conditional Lie-B?cklund for Nonlinear Diffusion Equation with Source Terms
摘要
Abstract
We considered with one kind of nonlinear diffusion equations with source terms which have many significant applications in physics and related sciences. Combing conditional Lie-Backlund symmetry with invariant subspace theory. We construct the nonlinear separable solutions for the nonlinear diffusion equations. A complete classification for the nonlinear diffusion equations.关键词
