嵌入维数为3的数值半群环的切锥

Tangent Cone of Numerical Semigroup Rings of Embedding Dimension Three

Yi-Huang Shen

摘要:

本文给出了切锥$\gr_\frakm(R)$的Buchsbaum和Cohen-Macaulay性质的新刻画,其中$(R,\frakm)$是嵌入维数为3的数值半群环.特别是,我们证实了Sapko对$\gr_\frakm(R)$的Buchsbaumness提出的猜想。

英文摘要:

In this paper, we give new characterizations of the Buchsbaum and Cohen-Macaulay properties of the tangent cone $\gr_\frakm(R)$, where $(R,\frakm)$ is a numerical semigroup ring of embedding dimension 3. In particular, we confirm the conjectures raised by Sapko on the Buchsbaumness of $\gr_\frakm(R)$.
