Degree bounds for Hopf actions on Artin–Schelter regular algebras

چکیده
We study semisimple Hopf algebra actions on Artin–Schelter regular algebras and prove several upper bounds the degrees of minimal generators invariant subring, syzygies modules over subring. These results are analogues for group commutative polynomial rings proved by Noether, Fogarty, Fleischmann, Derksen, Sidman, Chardin, Symonds.

متن کاملCoherent Unit Actions on Regular Operads and Hopf Algebras
J.-L. Loday introduced the concept of coherent unit actions on a regular operad and showed that such actions give Hopf algebra structures on the free algebras. Hopf algebras obtained this way include the Hopf algebras of shuffles, quasi-shuffles and planar rooted trees. We characterize coherent unit actions on binary quadratic regular operads in terms of linear equations of the generators of th...
متن کاملActions of Hopf algebras on noncommutative algebras
Often A is called H-module algebra. We refer reader to [11, 6] for the basic information concerning Hopf algebras and their actions on associative algebras. Definition 1.2 The invariants of H in A is the set AH of those a ∈ A, that ha = ε(h)a for each h ∈ H. Straightforward computations show, that AH is subalgebra of A. The notion of action of Hopf algebra on associative algebra generalize the ...

متن کاملActions of Hopf algebras ∗
An action of a finite dimensional Hopf algebra H on a noncommutative associative algebra A is considered. Properties of A , the subalgebra of invariants in A, are studied. It is proved that if A is integral over Z(A), the centre of an algebra A, then A is integral over Z(A) H , the subalgebra of invariants in Z(A), for each of three cases: 1. the coradical H0 is cocommutative and char k = p > 0...
