摘要:

基于Ehrhart $h^*$ -多项式的格多面体的特征刻画是一个困难的公开问题。本文完成了格多面体的分类,它的$h^*$ -多项式满足两个性质:它们是回文的(所以多面体是Gorenstein),它们正好由三项组成。这扩展了由于Batyrev和Juny的Gorenstein二度多面体的分类。证明依赖于最近的表征Batyrev和Hofscheier的空格单纯形的$h^*$ -多项式有两个条款。把我们的定理的角度来看,我们给出了这些和其他现有的结果在这方面的总结。

英文摘要:

The characterization of lattice polytopes based upon information about their Ehrhart $h^*$-polynomials is a difficult open problem. In this paper, we finish the classification of lattice polytopes whose $h^*$-polynomials satisfy two properties: they are palindromic (so the polytope is Gorenstein) and they consist of precisely three terms. This extends the classification of Gorenstein polytopes of degree two due to Batyrev and Juny. The proof relies on the recent characterization of Batyrev and Hofscheier of empty lattice simplices whose $h^*$-polynomials have precisely two terms. Putting our theorem in perspective, we give a summary of these and other existing results in this area.
