关于格理想的广义Scarf复形

On the generalized Scarf complex of lattice ideals

Hara Charalambous, Apostolos Thoma

摘要:

设$k$是一个域,$ \mathcal{L}\subset \mathbb{Z}^n$是一个格,使得$Ł\cap \mathbb{N}^n=\{{\bf 0}\}$和$I_Ł\subset \Bbbk[x_1,..., x_n]$是相应的格理想。我们提出了$I_Ł$的广义Scarf复形,并证明了它是不可缺少的,因为它包含在$R/I_Ł$的每个最小自由分解中。

英文摘要:

Let $k$ be a field, $ \mathcal{L}\subset \mathbb{Z}^n$ be a lattice such that $Ł\cap \mathbb{N}^n=\{{\bf 0}\}$, and $I_Ł\subset \Bbbk[x_1,..., x_n]$ the corresponding lattice ideal. We present the generalized Scarf complex of $I_Ł$ and show that it is indispensable in the sense that it is contained in every minimal free resolution of $R/I_Ł$.
