Graded algebras with prescribed Hilbert series
Abstract
For any power series with exponentially bounded nonnegative integer coefficients we suggest a simple construction of a finitely generated monomial associative algebra with Hilbert series very close to . If is rational/algebraic/transcendental, then the same is . If the growth of the coefficients of is polynomial, in the same way we construct a graded algebra preserving the polynomial growth of the coefficients of its Hilbert series . Applying a classical result of Fatou from 1906 we obtain that if a finitely generated graded algebra has a finite Gelfand-Kirillov dimension, then its Hilbert series is either rational or transcendental. In particular the same dichotomy holds for the Hilbert series of finitely generated algebras with polynomial identity.
