On the Ratliff-Rush closure of an ideal of a one-dimensional ring
Veronica Crispin Quinonez, Marco D'Anna, Vincenzo Micale
Let be an ideal in a Noetherian ring and let be its Ratliff-Rush closure. In this paper we study the asymptotic Ratliff-Rush number, i.e. $h(I)=\min\{n\in\m…

On ideals generated by two generic quadratic forms in the exterior algebra
Veronica Crispin Quiñonez, Samuel Lundqvist, Gleb Nenashev
Based on the structure theory of pairs of skew-symmetric matrices, we give a conjecture for the Hilbert series of the exterior algebra modulo the ideal generated by two generic qua…
