Interpolation matrices and jumping lines of logarithmic bundles
Elena Guardo, Graham Keiper, Grzegorz Malara
We study jumping lines loci of logarithmic bundles associated with finite sets of points in the projective plane. Using the interpolation matrix introduced in [DMTG25], we describe…

Symbolic Powers of Toric Ideals
Giuseppe Favacchio, Graham Keiper
This paper investigates the symbolic powers of toric ideals. We first describe them in terms of the kernel of certain linear maps derived from the lattice structure of the toric id…
