燃烧理论中抛物方程组全局解的存在性和不存在性
Existence and Non-existence of Global Solutions for Parabolic Systems from Combustion Theory
摘要
Abstract
The author considered the properties of solutions of initial boundary value problems for quasilinear parabolic systems from combustion theory,and obtained sufficient conditions for the existence and non-existence of global solutions by using energy estimation method,Jensen inequality and Gronwall inequality.The results show that there is a global non negative solution to the problem if the parameter m in the equation is odd and the initial value satisfies appropriate integrability conditions;and the solution of the problem will blow up at a finite time if m is even and the integral of the initial value is suitably large.关键词
