具奇异系数的耦合反应-对流-扩散方程组的临界 Fujita 曲线
Critical Fujita Curves for a Coupled Reaction-Convection-Diffusion System with Singular Coefficients
摘要
Abstract
Using the comparison of energy and constructing selfsimilar supersolutions,the author studied the homogeneous Neumann exterior problem of a coupled reaction-convection-diffusion system with singular coefficients.The critical Fujita curve,which described whether solutions exist globally or not,was determined and the blowing up theorem of Fujita type was established.This critical Fujita curve depends on the spacial dimension,convection and reaction terms of the system.关键词
