摘要
In this note, we combine the work of Ilmanen [11] and of Colding et al. [3] to observe a uniqueness property for tangent flows at the first singular time of a smooth mean curvature flow of a closed surface in R-3. Specifically, if, at a fixed singular point, one tangent flow is a positive integer multiple of a shrinking R-2, S-1 x R or S-2, then, modulo rotations, all tangent flows at the point are the same.
