The ramifications of the centres: quantised function algebras at roots of unity

K. A. Brown, I. Gordon

Let H be a Hopf algebra which is a finite module over a central sub-Hopf algebra R. We continue the study of such algebras begun in RT/9911234, concentrating in this case on the ex…

The ramification of centres: Lie algebras in positive characteristic and quantised enveloping algebras

K. A. Brown, I. Gordon

Let H be a Hopf algebra which is a finite module over a central sub-Hopf algebra R. The ramification behaviour of the maximal ideals of Z(H) with respect to the subalgebra R is stu…
