Enumeration of $\C{H}$-strata in quantum matrices with respect to dimension

Jason Bell, Karel Casteels, Stéphane Launois

We present a combinatorial method to determine the dimension of $\C{H}$-strata in the algebra of $m\times n$ quantum matrices $\Oq$ as follows. To a given $\C{H}$-stratum we associ…
