摘要：
We classify all noetherian Hopf algebras H over an algebraically closed field k of characteristic zero which are integral domains of Gelfand-Kirillov dimension two and satisfy the condition Ext(H)(1)(k,k) not equal 0. The latter condition is conjecturally redundant, as no examples are known (among noetherian Hopf algebra domains of GK-dimension two) where it fails. (C) 2009 Elsevier Inc. All rights reserved.
