关于BV函数全变差解耦公式
On formulae decoupling the total variation of BV functions
摘要:
在本文中,我们证明了几个公式,使一个捕获的奇异部分的测量导数的有界变差函数作为一个限制的非局部泛函。一个特殊的情况表明,重新缩放的分数拉普拉斯的功能$u\in SBV$严格收敛到奇异部分的$Du$。
英文摘要:
In this paper we prove several formulae that enable one to capture the singular portion of the measure derivative of a function of bounded variation as a limit of non-local functionals. One special case shows that rescalings of the fractional Laplacian of a function $u\in SBV$ converge strictly to the singular portion of $Du$.
