摘要

我们建立了从正则局部 Lipschitz 准凸函数的几乎每一点出发的最陡下降曲线的存在性，其中正则性意味着由子级集引起的扫频过程流是可逆的。然后，我们利用最大卷积来正则化一般的类凸函数，并在更一般的情况下获得了性质相同的结果。

Steepest Geometric Descent for Regularized Quasiconvex Functions

We establish existence of steepest descent curves emanating from almost every point of a regular locally Lipschitz quasiconvex functions, where regularity means that the sweeping process flow induced by the sublevel sets is reversible. We then use max-convolution to regularize general quasiconvex functions and obtain a result of the same nature in a more general setting.
