论文摘要
在本文中,我们使用生成函数方法来记录和计算多面体的Minkowski张量的条目。我们专注于“表面张量”,扩展了Arxiv中使用的方法:1807.10258对于与体积张量相对应的均匀分布的矩。在这种情况下,我们还将伴随多项式的定义扩展到具有简单方面的多层边界复合体。在简单多面的情况下,我们为这些表面张量提供了明确的配方。
In this paper we use a generating function approach to record and calculate entries of the Minkowski tensors of a polytope. We focus on ''surface tensors'', extending the methods used in arXiv:1807.10258 for moments of the uniform distribution which correspond to volume tensors. In this context we also extend the definition of the adjoint polynomial to the boundary complex of a polytope with simplicial facets. In the case of simplicial polytopes we give an explicit formulation for these surface tensors.
