Density of $f$ -ideals and $f$ -ideals in mixed small degrees

Huy TÀi HÀ, Graham Keiper, Hasan Mahmood +1

A squarefree monomial ideal is called an $f$ -ideal if its Stanley-Reisner and facet simplicial complexes have the same $f$ -vector. We show that $f$ -ideals generated in a fixed degr…

Regularity and h-polynomials of toric ideals of graphs

Giuseppe Favacchio, Graham Keiper, Adam Van Tuyl

For all integers $4 \leq r \leq d$ , we show that there exists a finite simple graph $G = G_{r, d}$ with toric ideal $I_{G} \subset R$ such that $R / I_{G}$ has (Castelnuovo-Mumford) regula…
