摘要: 研究一类带附加应力扩散项的Johnson-Segalman模型, 通过不变流形分析方法以及同宿轨与异宿轨的研究, 刻画了该模型的相空间结构, 并证明了一类具有三井位势的Hamilton系统同宿轨和异宿轨的存在性.

关键词: 三井位势, 同宿与异宿轨道, Johnson-Segalman流体模型

Abstract: In this paper, we considered a class of Johnson-Segalman (JS) models involving reaction diffusion. The model is prsented as nonlinear reaction diffusion equations. By virtue of invariant manifolds and study of homoclinic and heteroclinic orbits, we described the structure of phase plane of JS model and gave enlighten global results on homoclinic and heteroclinic bifurcation in a Hamiltonian system with 3wells potential.

Key words: 3-wells potential, homoclinic and heteroclinic orbit, JohnsonSegalman fluid model
