关于强耦合抛物型方程组平均振荡的小性与弱解的正则性:正则与退化情形

On the smallness of mean oscillations and regularity of weak solutions to regular/degenerate strongly coupled parabolic systems

Dung Le

AI总结:

本文研究正则与退化强耦合抛物型方程组,证明有界弱解的平均振荡在小球中很小,并在正则椭圆情形下得到Hölder连续性及全局存在性,同时探讨了多孔介质型退化方程组的弱解性质。

摘要:

本文将证明强耦合抛物型方程组的有界弱解在小球中的平均振荡很小。若方程组是正则椭圆的,则其有界弱解是Hölder连续的。对方程组的进一步假设甚至将证明这些解全局存在。本文还研究了多孔介质型退化方程组的弱解。

英文摘要:

It will be established that the mean oscillation of bounded weak solutions to strongly coupled parabolic systems is small in small balls. If the systems are regular elliptic then their bounded weak solutions are Hölder continuous. Further assumptions on the systems will even prove that these solutions exist globally. Weak solutions to degenerate systems of porous media type are also studied.
