关于Sobolev范数和全变差非局部逼近的相互作用律的形状因子

On the shape factor of interaction laws for a non-local approximation of the Sobolev norm and the total variation

Clara Antonucci, Massimo Gobbino, Matteo Migliorini, Nicola Picenni

摘要:

我们考虑由H. Brezis和H.- M. Nguyen在最近的一篇论文中说。这些泛函伽玛收敛于索伯列夫范数或全变差的倍数,具体取决于可和性指数,但在许多情况下常数的确切值是未知的。我们描述了一种新的方法,伽玛收敛的结果,导致在某些特殊情况下的常数的精确值,并存在光滑的恢复家庭。

英文摘要:

We consider the family of non-local and non-convex functionals introduced by H. Brezis and H.-M. Nguyen in a recent paper. These functionals Gamma-converge to a multiple of the Sobolev norm or the total variation, depending on a summability exponent, but the exact values of the constants are unknown in many cases. We describe a new approach to the Gamma-convergence result that leads in some special cases to the exact value of the constants, and to the existence of smooth recovery families.
