摘要:

用能量估计方法研究一类生物种群竞争模型(强耦合的捕食-食饵模型)在高维空间中整体解的存在性. 该模型包括(自我)扩散和交叉扩散, 且交叉扩散具有v/(1+ul)的形式.

关键词: 存在性, 整体解, 竞争模型, 方程组

Abstract:

The energy estimation method was used to investigate the existence of the global solutions for a class of competition system (strongly coupled preypredator model) in high dimension space. This class of competition system involves (self) diffusion and crossdiffusion, and the crossdiffusion is of the form v/(1+ul).

Key words: existence, global solution, competition system, equations
