Matroid correspondence
Colin Crowley, Changxin Ding, Haoxi Hu +7
Motivated by algebraic correspondences and linear operators associated with volume and Lorentzian polynomials, we introduce matroid correspondences and their polymatroid analogues.…
Twice-Marked Banana Graphs & Brill-Noether Generality
Nathan Pflueger, Noah Solomon
We analyze a family of graphs known as banana graphs, with two marked vertices, through the lens of Hurwitz-Brill-Noether theory. As an application, we construct explicit new examp…
On some notions of rank for matrices over tracts
Matthew Baker, Noah Solomon, Tianyi Zhang
Given a tract in the sense of Baker and Bowler and a matrix with entries in , we define several notions of rank for . In this way, we are able to unify and find conce…
Cohomology Groups of Deformations of Line Bundles on Complex Tori
O. Ben-Bassat, N. Solomon
The cohomology groups of line bundles over complex tori (or abelian varieties) are classically studied invariants of these spaces. In this article, we compute the cohomology groups…
