Regularity 3 in edge ideals associated to bipartite graphs

Oscar Fernández-Ramos, Philippe Gimenez

We focus in this paper on edge ideals associated to bipartite graphs and give a combinatorial characterization of those having regularity 3. When the regularity is strictly bigger…

First Nonlinear Syzygies of Ideals Associated to Graphs

Oscar Fernandez-Ramos, Philippe Gimenez

Consider an ideal $I \subset K [x_{1}, ..., x_{n}]$ , with $K$ an arbitrary field, generated by monomials of degree two. Assuming that $I$ does not have a linear resolution, we determine t…
