Signature invariants of monomial ideals

Jovanny Ibarguen, Carlos E. Valencia, Rafael H. Villarreal

Let $I$ be a monomial ideal of a polynomial ring $R = K [x_{1}, \dots, x_{n}]$ over a field $K$ and let $sgn (I)$ be its signature ideal. If $I$ is not a principal ideal, we show that…

A note on Rees algebras and the MFMC property

I. Gitler, C. E. Valencia, R. H. Villarreal

We study irreducible representations of Rees cones and characterize the max-flow min-cut property of clutters in terms of the normality of Rees algebras and the integrality of cert…
