Separating monomials for diagonalizable actions
M. Domokos · Repository of the Academy's Library (Library of the Hungarian Academy of Sciences) · 2022
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.
