Cohen-Macaulay rings and polynomials with real zeros



Let a(t) be a polynomial which has positive integer coefficients, a constant term of one, and only real zeros. We show that a(t) appears in the numerator of the Hilbert series of some Cohen-Macaulay ring, and present some evidence in favor of the stronger conjecture that a(t) is the f-polynomial of a simplicial complex.

This is joint work with Jason Bell.
