Neckpinch Dynamics for Asymmetric Surfaces Evolving by Mean Curvature Flow
by Gang Zhou, Dan Knopf, and Israel Michael Sigal
Published 1 May 2018
The authors study noncompact surfaces evolving by mean curvature flow (mcf). For an open set of initial data that are $C^3$-close to round, but without assuming rotational symmetry or positive mean curvature, the authors show that mcf solutions become singular in finite time by forming neckpinches, and they obtain detailed asymptotics of that singularity formation. The results show in a precise way that mcf solutions become asymptotically rotationally symmetric near a neckpinch singularity.
