Exact Traveling Wave Solutions Burgers-Huxley Equation

JIA Huilin WEN Zhenshu ZHANG Xiaoya

Abstract: Various kinds exact traveling wave solutions Burgers-Huxley equation by using (G/G) -expansion method and F -expansion method are obtained respectively. The research results show that one can only obtain the solutions Burgers-Huxley equation under the condition λ2-4μ>0 by (G/G) -expansion method, while one can only find the solutions Burgers-Huxley equation under some special conditions by Fδ -expansion method.

Keywords: Burgers-Huxley equation; (G′/G) -expansion method; F -expansion method;exact traveling wave solution

1預備知識

Burgers-Huxley(BH)方程是一類重要的非線性反應擴散方程,其形式為

ut+pux-uxx+qu(u-1)(u-s)=0o

式(1)中: ?,q,s 均為非零常數(shù)。(剩余5459字)
