The Structure of Translating Surfaces with Finite Total Curvature

Abstract

In this paper, we prove that any mean curvature flow translator ${\Sigma }^2\subset {\mathbb{R}}^3$ with finite total curvature and one end must be a plane. We also prove that if the translator $\Sigma$ has multiple ends, they are asymptotic to a plane $\Pi$ containing the direction of translation and can be written as graphs over $\Pi$. Finally, we determine that the ends of $\Sigma$ are strongly asymptotic to $\Pi$ and obtain quantitative estimates for their asymptotic behavior.
