单纯复形的余维Cohen-Macaulay性与展开函子

Cohen-Macaulay-ness in codimension for simplicial complexes and expansion functor

Rahim Rahmati-Asghar

摘要:

本文证明了Buchsbaum单纯复形的展开式是$CM_t$,对于最优整数$t\geq 1$ .此外,通过对$CM_t$单纯复形施加额外的假设,我们证明了它可以从Buchsbaum复形得到。

英文摘要:

In this paper we show that expansion of a Buchsbaum simplicial complex is $CM_t$, for an optimal integer $t\geq 1$. Also, by imposing extra assumptions on a $CM_t$ simplicial complex, we prove that it can be obtained from a Buchsbaum complex.
