Zassenhaus varieties of general linear Lie algebras
Let g be a Lie algebra over an algebraically closed field of characteristic p>0 and let U be the universal enveloping algebra of g. We prove in this paper for g=gl_n and g=sl_n that the centre Z of U is a unique factorisation domain and that its field of fractions is rational. For g=sl_n our argu...
