关于局部Lipschitz和正则函数的误差界模

On Error Bound Moduli for Locally Lipschitz and Regular Functions

Minghua Li, Kaiwen Meng, Xiaoqi Yang

摘要:

本文研究了局部Lipschitz正则函数通过其外极限次微分集的局部误差界模。我们表明,0的距离从外部限制次微分的支撑函数的次微分集,这本质上是0的距离从结束设置的次微分集,是一个上估计的局部误差界模。在一定的正则性条件下,对于凸函数,这个上估计是紧的。我们表明,0的距离从外部限制次微分集的一个较低的$\mathcal{C}^1$功能是等于局部误差界模。

英文摘要:

In this paper we study local error bound moduli for a locally Lipschitz and regular function via its outer limiting subdifferential set. We show that the distance of 0 from the outer limiting subdifferential of the support function of the subdifferential set, which is essentially the distance of 0 from the end set of the subdifferential set, is an upper estimate of the local error bound modulus. This upper estimate becomes tight for a convex function under some regularity conditions. We show that the distance of 0 from the outer limiting subdifferential set of a lower $\mathcal{C}^1$ function is equal to the local error bound modulus.
