Induced matchings and the v-number of graded ideals
Gonzalo Grisalde, Enrique Reyes, Rafael H. Villarreal
We give a formula for the v-number of a graded ideal that can be used to compute this number. Then we show that for the edge ideal of a graph the induced matching number…

Rees algebras of filtrations of covering polyhedra and integral closure of powers of monomial ideals
Gonzalo Grisalde, Alexandra Seceleanu, Rafael H. Villarreal
The aims of this work are to study Rees algebras of filtrations of monomial ideals associated to covering polyhedra of rational matrices with non-negative entries and non-zero colu…
