K-classes of delta-matroids and equivariant localization
Christopher Eur, Matt Larson, Hunter Spink
Delta-matroids are "type B" generalizations of matroids in the same way that maximal orthogonal Grassmannians are generalizations of Grassmannians. A delta-matroid analogue of the…

Rank functions and invariants of delta-matroids
Matt Larson
In this note, we give a rank function axiomatization for delta-matroids and study the corresponding rank generating function. We relate an evaluation of the rank generating functio…

Kazhdan-Lusztig polynomials of braid matroids
Luis Ferroni, Matt Larson
We provide a combinatorial interpretation of the Kazhdan--Lusztig polynomial of the matroid arising from the braid arrangement of type , which gives an interpreta…
