分次Cohen-Macaulay整环与具有短$h$ -向量的格多面体

Graded Cohen-Macaulay domains and lattice polytopes with short $h$-vector

Lukas Katthän, Kohji Yanagawa

摘要:

设P是具有$h^*$ -向量$(1, h^*_1, h^*_2)$的格多面体.本文证明了如果$h_2^* \leq h_1^*$,则$P$是IDP。更一般地,我们给出了代数闭域上半标准分次Cohen-Macaulay域的相应结果.

英文摘要:

Let P be a lattice polytope with $h^*$-vector $(1, h^*_1, h^*_2)$. In this note we show that if $h_2^* \leq h_1^*$, then $P$ is IDP. More generally, we show the corresponding statements for semi-standard graded Cohen-Macaulay domains over algebraically closed fields.
