Abstract

In this talk, we will introduce exponential time differencing schemes for Allen-Cahn equations. Maximum bound principle and energy stability of Allen-Cahn equations will be proved in the discrete time sense. We will also study an image segmentation problem with the proposed numerical algorithm.
