On the Poincaré series of quadratic algebras associated to Hecke symmetries

Hecke symmetries generalize the usual tensor symmetry of vector spaces
as well as the symmetry of vector superspaces. To a Hecke symmetry there associates a quadratic algebra which can be interpreted as the function algebra upon a certain quantum space. This paper investigates the Poincaré series of this quadratic algebra. We show that it is a rational function with numerator and denominator being a reciprocal polynomial and a skew-reciprocal polynomial, respectively.
