GENERALISED QUANTUM DETERMINANTAL RINGS ARE MAXIMAL ORDERS
Published online by Cambridge University Press: 04 August 2020
Abstract
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.
