Hidden Symmetry of the Differential Calculus on the Quantum Matrix Space
S. Sinel'shchikov, L. Vaksman
Abstract
A standard bicovariant differential calculus on a quantum matrix space Mat(m,n)q is considered. The principal result of this work is in observing that the Uqs(glm× gln))q is in fact a Uqsl(m+n)-module differential algebra.
