Noetherian Hopf Algebra Domains of Gelfand-kirillov Dimension Two
نویسندگان
چکیده
We classify all noetherian Hopf algebras H over an algebraically closed field k of characteristic zero which are integral domains of GelfandKirillov dimension two and satisfy the condition ExtH(k, k) 6= 0. The latter condition is conjecturally redundant, as no examples are known (among noetherian Hopf algebra domains of GK-dimension two) where it fails.

Homogenized Down-up Algebras
This paper studies two homogenizations of the down-up algebras introduced in [1]. We show that in all cases the homogenizing variable is not a zero-divisor, and that when the parameter β is non-zero, the homogenized down-up algebra is a Noetherian domain and a maximal order, and also Artin-Schelter regular, Auslander regular, and Cohen-Macaulay. We show that all homogenized down-up algebras hav...
متن کاملHopf algebras under finiteness conditions
This is a brief survey of some recent developments in the study of infinite dimensional Hopf algebras which are either noetherian or have finite Gelfand-Kirillov dimension. A number of open questions are listed.
متن کاملCentralizers in Domains of Finite Gelfand-kirillov Dimension
We study centralizers of elements in domains. We generalize a result of the author and Small [4], showing that if A is a finitely generated noetherian domain and a ∈ A is not algebraic over the extended centre of A then the centralizer of a has Gelfand-Kirillov dimension at most one less than the Gelfand-Kirillov dimension of A. In the case that A is a finitely generated noetherian domain of GK...
متن کاملHomological Integral of Hopf Algebras
The left and right homological integrals are introduced for a large class of infinite dimensional Hopf algebras. Using the homological integrals we prove a version of Maschke’s theorem for infinite dimensional Hopf algebras. The generalization of Maschke’s theorem and homological integrals are the keys to studying noetherian regular Hopf algebras of Gelfand-Kirillov dimension one.
متن کاملThe Gelfand-Kirillov Dimension of Rings with Hopf Algebra Action
Let k be a perfect field, H a irreducible cocommutative Hopf k-algebra and P (H) the space of primitive elements of H, R a k-algebra on which acts locally finitely H and R#H the associated smash product. Assume that H is almost solvable with P (H) finite-dimensional n and the sequences of divided powers are all infinite. Then the Gelfand-Kirillov dimension of R#H is GK(R) + n.
