反應擴散對流方程的傳動波解

Abstract

本論文分成兩部份。 第一部份是關於反應擴散對流方程 的傳動波解。我們考慮具有週期性的對流場 、燃燒型態及半穩定的非線性反應項 。我們主要整理Berestycki和Hamel文章[1]中的脈衝波的存在性、唯一性及單調性結 果。第二部份主要是處理三種競爭物種Lotka-Volterra系統的確切傳動波解。

There are two parts in this paper. Part I is concerned with the travelling wave solutions for reaction-diffusion-advection equations . We consider periodic advection and combustion, monostable nonlinear reaction term . We mainly survey the results of existence, uniqueness, and monotonicity of pulsating waves from the paper by Berestycki and Hamel [1]. Part II deals with exact travelling wave solutions of competitive Lotka-Volterra systems of three species.
