J. Reine Angew. Ehrhart多项式、简单多面体、幻方和Stanley的猜想。数学。,出现。研究了一种有效的技术来证明来自压缩多面体的Gorenstein序列是单峰的。在本文中,我们将利用这一技术寻找一类由有限图产生的具有单峰h向量的丰富的Gorenstein环。
Athanasiadis [Ehrhart polynomials, simplicial polytopes, magic squares and a conjecture of Stanley, J. Reine Angew. Math., to appear.] studies an effective technique to show that Gorenstein sequences coming from compressed polytopes are unimodal. In the present paper we will use such the technique to find a rich class of Gorenstein toric rings with unimodal h-vectors arising from finite graphs.
