The aim of this paper is to present several properties of the nonnegative weak solutions to a class of very singular equations whose prototype is ut=div(um1|Du|p2Du),p>1and3p<m+p<2.Namely, we prove Llocr and LlocrLloc estimates and Harnack estimates. Note that 3p=m+p is a critical value: under this threshold the energy estimates hold with a reverse sign.

一类双重非线性非常奇异抛物方程的正则性结果

本文的目的是介绍一类非常奇异方程的非负弱解的一些性质,其原型为 üŤ=divü-1个|dü|p-2düp>1个3-p<+p<2即,我们证明 大号位置[R大号位置[R-大号位置估计和Harnack估计。注意3-p=+p 是一个临界值:在此阈值下,能量估算值带有一个反向符号。
