Global Existence and Blow-up for a Degenerate Parabolic System Come from Logarithmic Function
摘要
Abstract
In this paper, a class of initial-boundary value problem of degenerate parabolic system come from logarithmic function was considered.The local existence of solution was proved by approximation method.The condition of global existence of the solution was obtained by the upper solution of the characteristic function, and the blow-up condition and the upper bound of the blow-up time were obtained by using the characteristic function.关键词
