Abstract

We classify all noetherian Hopf algebras HH over an algebraically closed field kk of characteristic zero which are integral domains of Gelfand-Kirillov dimension two and satisfy the condition \ExtH1(k,k)0\Ext^1_H(k,k)\neq 0. The latter condition is conjecturally redundant, as no examples are known (among noetherian Hopf algebra domains of GK-dimension two) where it fails.
