MiS Preprint Repository

We have decided to discontinue the publication of preprints on our preprint server as of 1 March 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV (www.arxiv.org) that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.

A representation formula for the inverse harmonic mean curvature flow

Knut Smoczyk

Abstract

Let $M_t$ be a smooth family of embedded, strictly convex hypersurfaces in $\mathbb R^{n+1}$ evolving by the inverse harmonic mean curvature flow $$\frac{d}{dt} F=\mathcal H^{-1}\nu.$$ Surprisingly, we can determine the explicit solution of this nonlinear parabolic equation with some Fourier analysis. More precisely, there exists a representation formula for the evolving hypersurfaces $M_t$ that can be expressed in terms of the heat kernel on $S^n$ and the initial support function.
