Koszul Property and Poincare' Series of Matrix-Bialgebras of Type $A

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/149552Bialgebras associated to Yang-Baxter operators satisfying the Hecke equation, are considered. It is shown that they are Koszul algebras. Their Poincare' series are calculated via the Poincare' series of the corresponding quantum spaces.15 pages, standard latex fileQuantum AlgebraKoszul Property and Poincare' Series of Matrix-Bialgebras of Type $A_N$text
