The flag f -vector is a basic combinatorial invariant of graded posets that counts the number of chains. For an Eulerian poset, its flag f -vector is efficiently encoded by a certain non-commutative polynomial, called the cd -index. In this note, we give an extensions of the cd -index ...

摘要:新华·国际金融中心发展指数(原新华-道琼斯国际金融中心发展指数,简称IFCD Index)是中国经济信息社积极参与共建“一带一路”国家的金融信息服务体系的体现,于2010年首次全球亮相,填补了亚太地区金融中心指数空白,一定程度上满足了“一带一路”国家对金融中心建设和金融信息指数服务的需求。
The goal of this article is to give a Lefschetz type decomposition for the cd-index of a complete fan. To a complete simplicial fan one can associate a toric variety X, the even Betti numbers h_i of X and the numbers g_i = h_i-h_{i-1}. If the fan is projective, then non-ne...
For Eulerian partially ordered sets, the flag vector can be encoded efficiently in the cd-index. The cd-index of a polytope has all positive entries. An important open problem is to give the broadest natural class of Eulerian posets having nonnegative cd-index. This paper completely determines...
This is a survey of the $cd$-index of Eulerian partially ordered sets. The $cd$-index is an encoding of the numbers of chains, specified by ranks, in the poset. It is the most efficient such encoding, incorporating all the affine relations on the flag numbers of Eulerian posets. Euleria...
