Abstract

A squarefree monomial ideal is called an ff-ideal if its Stanley-Reisner and facet simplicial complexes have the same ff-vector. We show that ff-ideals generated in a fixed degree have asymptotic density zero when the number of variables goes to infinity. We also provide novel algorithms to construct ff-ideals generated in small degrees.
