Sharp Convergence to the Half-Space for Mullins-Sekerka in the Plane

Wenhui Shi, Maria G. Westdickenberg, Michael Westdickenberg

We revisit the HED Method for the Mullins-Sekerka evolution in the plane. We identify a natural notion of distance, intrinsic to the interface itself. Using this distance, the ener…

Optimal regularity for the variable coefficients parabolic Signorini problem

Vedansh Arya, Wenhui Shi

In this paper we discuss the optimal regularity of the variable coefficient parabolic Signorini problem with $W_{p}^{1, 1}$ coefficients and $L^{p}$ inhomogeneity, where $p > n + 2$ with $n…
