An $L^1$ method for convergence and metastability

We present a novel method developed for the 1-d Cahn Hilliard equation in Otto, Scholtes, and W. (2019) and extended in Biesenbach, Schubert, and W. (2021). We also mention work in progress with Otto and Schubert in which this method is applied to the Mullins Sekerka evolution in dimensions 2 and 3.
