单轨道的等变Hilbert级数

Equivariant Hilbert Series of Monomial Orbits

Sema Gunturkun, Uwe Nagel

摘要:

确定了由单项式的轨道在严格增函数幺半群$\mbox{Inc}(\mathbb{N})$作用下生成的理想的等变Hilbert级数。这是用来找到这样一个理想的维数和程度。结果还表明,Nagel和Römer给出的关于任意$\mbox{Inc}(\mathbb{N})$-不变理想的等变Hilbert级数的分母的描述是相当有效的.

英文摘要:

The equivariant Hilbert series of an ideal generated by an orbit of a monomial under the action of the monoid $\mbox{Inc}(\mathbb{N})$ of strictly increasing functions is determined. This is used to find the dimension and degree of such an ideal. The result also suggests that the description of the denominator of an equivariant Hilbert series of an arbitrary $\mbox{Inc}(\mathbb{N})$-invariant ideal as given by Nagel and Römer is rather efficient.
