Comparing invariants of toric ideals of bipartite graphs

Abstract

Let $G$ be a finite simple graph and let $I_G$ denote its associated toric ideal in the polynomial ring $R$. For each integer $n\geq 2$, we completely determine all the possible values for the tuple $({\rm reg}(R/I_G), {\rm deg}(h_{R/I_G}(t)),{\rm pdim}(R/I_G), {\rm depth}(R/I_G),\dim(R/I_G))$ when $G$ is a connected bipartite graph on $n$ vertices.
