关于Gorenstein单项曲线的一个注记

A note on Gorenstein monomial curves

Philippe Gimenez, Hema Srinivasan

摘要:

设$k$为任意字段。本文证明了:若一个互质正整数序列${\bf a}=(a_1,a_2,a_3,a_4)$在${\mathbb A}_k^4$中定义了一条Gorenstein非完全交单项曲线${\mathcal C}({\bf a})$,则存在两个向量${\bf u}$和${\bf v}$,使得对几乎所有$t\geq 0$,${\mathcal C}({\bf a}+t{\bf u})$和${\mathcal C}({\bf a}+t{\bf v})$也是Gorenstein非完全交仿射单项曲线.

英文摘要:

Let $k$ be an arbitrary field. In this note, we show that if a sequence of relatively prime positive integers ${\bf a}=(a_1,a_2,a_3,a_4)$ defines a Gorenstein non complete intersection monomial curve ${\mathcal C}({\bf a})$ in ${\mathbb A}_k^4$, then there exist two vectors ${\bf u}$ and ${\bf v}$ such that ${\mathcal C}({\bf a}+t{\bf u})$ and ${\mathcal C}({\bf a}+t{\bf v})$ are also Gorenstein non complete intersection affine monomial curves for almost all $t\geq 0$.
