Graphs of relations and Hilbert series

Journal of Symbolic Computation, 2007
We are discussing certain combinatorial and counting problems related to quadratic algebras. First we give examples which confirm the Anick conjecture on the minimal Hilbert series for algebras given by n generators and n(n-1)/2 relations for n less or equal then 7. Then we investigate combinatorial structure of colored graph associated to relations of

On the Hilbert series of monomial ideals

Journal of Combinatorial Theory - Series A, 2013
AbstractTo every squarefree monomial ideal one can associate a hypergraph. In this paper we show that the Hilbert series of a squarefree monomial ideal can be obtained from the so-called edge induced polynomial of the associated hypergraph.

On the computation of hilbert—Poincaré series

Applicable Algebra in Engineering, Communication and Computing, 1991
Let k be a field, \(X_ 1,...,X_ n\) indeterminates, \(R=k[X_ 1,...,X_ n]\) (graded by \(\deg (X_ i)=1)\) and I a homogeneous ideal of R. For a term ordering s, \(Lt_ s(I)\) is the leading term ideal associated to I with respect to s. It is known that the Hilbert- Poincaré series of R/I and \(R/Lt_ s(I)\) are the same - a result by F. S.

The Hilbert Series of the Clique Complex

Graphs and Combinatorics, 2005
For a graph G, we show a theorem that establishes a correspondence between the fine Hilbert series of the Stanley-Reisner ring of the clique complex for the complementary graph of G and the fine subgraph polynomial of G. We obtain from this theorem some corollaries regarding the independent set complex and the matching complex.

Computing noncommutative Hilbert series

ACM Communications in Computer Algebra, 2019
We propose methods for computing the Hilbert series of multigraded right modules over the free associative algebra. In particular, we compute such series for noncommutative multigraded algebras. Using results from the theory of regular languages, we provide conditions when the methods are effective and hence the Hilbert series have a rational sum ...
