Face Numbers of Certain Cohen-Macaulay Flag Complexes

Combinatorics 2010-10-13 v1

Abstract

We show that if a dd-dimensional Cohen-Macaulay complex is, in a certain sense, sufficiently "close" to being balanced, then there is a dd-dimensional balanced Cohen-Macaulay complex having the same ff-vector. This in turn provides some partial evidence for a conjecture of Kalai on the ff-vectors of Cohen-Macaulay flag complexes.
