Generalised quantum determinantal rings are the analogue in quantum matrices
of Schubert varieties. Maximal orders are the noncommutative version of
integrally closed rings...In this paper, we show that generalised quantum
determinantal rings are maximal orders. The cornerstone of the proof is a
description of generalised quantum determinantal rings, up to a localisation,
as skew polynomial extensions.(read more)
