摘    要:通过中心流形约化方法,将广义Burgers—Fisher方程投影到稳定流行和不稳定流行上.然后利用中心流形函数,得到了该方程的平衡解(μ,λ)=(0,λ)从点(0,a)处分歧出一个同胚于S^1的吸引子.

关 键 词:Burgers—Fisher方程  分歧方程  吸引子

Abstract:Generalized Burgers--fisher equation is projected into stable manifold and unstable manifold by the central manifold reduction method. The equilibrium solution (μ,λ) = (0,λ) of the equation bifurcates an attractor which is homeomorphism toS^1 by central manifold function.
Keywords:Burgers-Fisher equation  bifurcated equation  S^1 attractor
