Symbolic Powers and Asymptotic Invariants of GL-Invariant Ideals

Sankhaneel Bisui, Alexandra Seceleanu

This work concerns ideals invariant under the action of the group of linear base changes on a generic matrix; we call these GL-invariant ideals. We determine the ordinary powers, t…

Corrigendum to "Higher Lorentzian polynomials,...in codimension two" [International Mathematics Research Notices, Volume 2025, Issue 13, July 2025, arXiv:2208.05653]

Pedro Macias Marques, Chris McDaniel, Alexandra Seceleanu

A homogeneous bivariate $d$ -form defines an $(i + 1)$ -rowed Toeplitz matrix for each $i$ between $0$ and $d$ . We use Hodge theory and Schur polynomials to prove that if the $(i + 1)$ -r…
