O_e(G) is a free module over O(G)

K. A. Brown, I. Gordon, J. T. Stafford

We show that the quantised function algebra O_e(G) of a simply-connected semisimple algebraic group G at a root of unity is a free module over the subring isomorphic to O(G).

Algebras without noetherian filtrations

J. T. Stafford, J. J. Zhang

We provide examples of finitely generated noetherian PI algebras for which there is no finite dimensional filtration with a noetherian associated graded ring; thus we answer negati…
