We study the homogeneous Dirichlet problem for a class of nonlocal singular parabolic equations utdiv|u|p[u]2u=fin Ω×(0,T),where ΩRd, d2, is a smooth bounded domain, p[u]=p(l(u)) is a given function with values in the interval [p,p+](1,2), and l(u)=Ω|u(x,t)|αdx, α[1,2], is a functional of the unknown solution. We find sufficient conditions for global or local in time solvability of the problem, prove the uniqueness, and show that every solution gets extinct in a finite time.

关于一类具有 p[üXŤ]-拉普拉斯算子

我们研究了一类非局部奇异抛物方程的齐次Dirichlet问题 üŤ-div|ü|p[ü]-2ü=F在 Ω×0Ť哪里 Ω[Rdd2,是一个光滑的有界域, p[ü]=pü 是给定的函数,其值在间隔内 [p-p+]1个2ü=Ω|üXŤ|αdXα[1个2],是未知解决方案的功能。我们为问题的整体或局部解决找到了充分的条件,证明了其唯一性,并表明每种解决方案在有限的时间内都将消失。
