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.
