与完全非线性算子退化或奇异有关的抛物问题的存在性结果

Existence results for parabolic problems related to fully non linear operators degenerate or singular

Francoise Demengel

摘要:

本文证明了在Omega时间]0,T[上带某些边界条件的抛物型方程dtu = F(Du,D2 u)+ f(x,u)的解的存在性和正则性,其中Omega是具有锥性质的有界区域,$F$是奇异的或退化的,并满足某些一致椭圆性条件.

英文摘要:

In this paper we prove some existence and regularity results concerning parabolic equations dtu = F(D u, D2 u) + f(x,u) with some boundary conditions, on Omega times ]0,T[, where Omega is some bounded domain which possesses the cone property and $F$ is singular or degenerate, with some uniform ellipticity conditions.
