FINITE GENERATION OF THE INVARIANTS OF FINITE-DIMENSIONAL HOPF-ALGEBRAS

[摘要] In this paper we prove, following closely the original E. Noether's proof for finite groups, that if H is a commutative finite dimensional Hopf Algebra and A is a commutative H-comodule algebra that is finitely generated over the base field, then the algebra A(H) of H-invariants of A is finitely generated.
