$2$ d Mumford-Shah极小元的端点正则性

Endpoint regularity of $2$d Mumford-Shah minimizers

Camillo De Lellis, Matteo Focardi

摘要:

证明了$2$维Mumford-Shah极小元在连通弧端点处的$\varepsilon$ -正则性定理.特别是,我们表明,如果在一个给定的球$B_r (x)$的跳跃集的一个给定的Mumford-Shah极小是足够接近,在Hausdorff距离,半径为$B_r (x)$,那么在一个较小的球的跳跃集是一个连接的弧终止于一些内点$y_0$和它是$C^{1,α}$到$y_0$。

英文摘要:

We prove an $\varepsilon$-regularity theorem at the endpoint of connected arcs for $2$-dimensional Mumford-Shah minimizers. In particular we show that, if in a given ball $B_r (x)$ the jump set of a given Mumford-Shah minimizer is sufficiently close, in the Hausdorff distance, to a radius of $B_r (x)$, then in a smaller ball the jump set is a connected arc which terminates at some interior point $y_0$ and it is $C^{1,α}$ up to $y_0$.
