关于由胶合得到的单项曲线

On monomial curves obtained by gluing

Raheleh Jafari, Santiago Zarzuela Armengou

摘要:

利用胶合的概念,研究了与仿射单项曲线相关联的切锥的算术性质。特别是,我们刻画了Cohen-Macaulay和Gorenstein性质的切锥的一些家庭的单式曲线得到的胶合。此外,我们提供了新的单式曲线族的非减希尔伯特函数。

英文摘要:

We study arithmetic properties of tangent cones associated to affine monomial curves, using the concept of gluing. In particular we characterize the Cohen-Macaulay and Gorenstein properties of tangent cones of some families of monomial curves obtained by gluing. Moreover, we provide new families of monomial curves with non--decreasing Hilbert functions.
