热带拟阵多面体的粗型

Coarse types of tropical matroid polytopes

Katja Kulas

摘要:

本文描述了热带拟阵多胞形的热带复形$C$的组合结构,得到了$C$的极大胞腔的粗型公式。由于热带复形和单项式理想的分解之间的联系,这产生了Dochtermann,Joswig和Sanyal最近的一篇论文中介绍的相应粗型理想的生成元(2010,预印本arXiv.org:1001.0237)。进而给出了一致热带拟阵多胞形的极小热带半空间,即热带超单形的完整刻画。

英文摘要:

Describing the combinatorial structure of the tropical complex $C$ of a tropical matroid polytope, we obtain a formula for the coarse types of the maximal cells of $C$. Due to the connection between tropical complexes and resolutions of monomial ideals, this yields the generators for the corresponding coarse type ideal introduced in a recent paper of Dochtermann, Joswig and Sanyal (2010, preprint arXiv.org:1001.0237). Furthermore, a complete description of the minimal tropical halfspaces of the uniform tropical matroid polytopes, i.e. the tropical hypersimplices, is given.
