热带地表奇点

Tropical surface singularities

Hannah Markwig, Thomas Markwig, Eugenii Shustin

摘要:

本文研究复曲面三重中奇异曲面的热带化问题。本文对极大维奇异热带曲面进行了完全分类,证明了它们一般只能有100多个奇点,并描述了所有可能的奇点位置。更精确地说,我们证明了奇点必须是顶点,或广义中点和重心的奇异热带曲面的某些面,在某些情况下,可能有额外的度量限制奇异热带曲面的面。

英文摘要:

In this paper, we study tropicalisations of singular surfaces in toric threefolds. We completely classify singular tropical surfaces of maximal-dimensional type, show that they can generically have only finitely many singular points, and describe all possible locations of singular points. More precisely, we show that singular points must be either vertices, or generalized midpoints and baricenters of certain faces of singular tropical surfaces, and, in some cases, there may be additional metric restrictions to faces of singular tropical surfaces.
