弱中曲率流的二阶导数Hölder估计

A second derivative Hölder estimate for weak mean curvature flow

Yoshihiro Tonegawa

摘要:

证明了单位密度假设下的Brakke中曲率流在时空中几乎处处光滑。更一般地说,如果速度在弱意义上等于它的中曲率加上某个给定的α-Hölder连续向量场,那么我们几乎处处证明C^{2,α}正则性。

英文摘要:

We give a proof that Brakke's mean curvature flow under the unit density assumption is smooth almost everywhere in space-time. More generally, if the velocity is equal in a weak sense to its mean curvature plus some given α-Hölder continuous vector field, then we show C^{2,α} regularity almost everywhere.
