Bases of the quantum matrix bialgebra and induced sign characters of the Hecke algebra
Ryan Kaliszewski, Justin Lambright, Mark Skandera
We combinatorially describe entries of the transition matrices which relate monomial bases of the zero-weight space of the quantum matrix bialgebra. This description leads to a com…
