论文摘要
在可对角线的群体作用下将Zariski封闭轨道分开的一组单元是根据角色组的零和序列的单粒子来表征的。这适用于比较分离不变式和产生可对角线分组动作的不变的程度界限。
Sets of monomials separating Zariski closed orbits under diagonalizable group actions are characterized in terms of the monoid of zero-sum sequences over the character group. This is applied to compare the degree bounds for separating invariants and generating invariants of diagonalizable group actions.
