QUASI-DETERMINANTS AND q-COMMUTING MINORS
Published online by Cambridge University Press: 25 August 2010
Abstract
We present two new proofs of the q-commuting property holding among certain pairs of quantum minors of a q-generic matrix. The first uses elementary quasi-determinantal arithmetic; the second involves paths in a directed graph. Together, they indicate a means to build the multi-homogeneous coordinate rings of flag varieties in other non-commutative settings.
