光滑单项曲线的Castelnuovo-Mumford正则性与约化数

Castelnuovo-Mumford regularity and reduction number of smooth monomial curves

Michael Hellus, Lê Tuân Hoa, Jürgen Stückrad

摘要:

我们比较,光滑单项射影曲线,卡斯特-诺沃-芒福德正则性和减少数,我们提出了一个例子,这两个数字不同。然而,我们证明了它们对某类单项曲线是coin-cide的.此外,对于光滑的单项曲线,我们证明了一个不等式,这是强于一个从艾森巴德-后藤猜想。

英文摘要:

We compare, for smooth monomial projective curves, the Castel- nuovo-Mumford regularity and the reduction number; we present an example where these two numbers differ. However, we show they coin- cide for a certain class of monomial curves. Furthermore, for smooth monomial curves we prove an inequality which is stronger than the one from the Eisenbud-Goto conjecture.
