Koszul property and Poincare series of matrix bialgebras of type A(n)

[摘要] Bialgebras, defined by means of Yang-Baxter operators which verify 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 planes. (C) 1997 Academic Press.
