具有齐次Neumann边界条件的抛物p-Laplace方程解的爆破以及不熄灭问题
Blow-up and Non-extinction of Solution to a Parabolic p-Laplace Equation with Homogeneous Neumann Boundary Conditions
摘要
Abstract
We study the blow-up and non-extinction of solution to a parabolic p-Laplace equation ut-div(| ▽u|p-2▽u)=|u|q-2 ulog | u |-1/|Ω|∫Ω|u|q-2ulog |u| dx,subject to homogeneous Neumann boundary value condition.For the case of 1<p<2,we prove that under the condition of non-positive initial energy,the solution blows up in finite time if q>2,and the solution does not extinct in finite time if 1<q≤p.关键词
