The combinatorics behind the leading Kazhdan-Lusztig coefficients of braid matroids
Alice L. L. Gao, Nicholas Proudfoot, Arthur L. B. Yang +1
Ferroni and Larson gave a combinatorial interpretation of the braid Kazhdan-Lusztig polynomials in terms of series-parallel matroids. As a consequence, they confirmed an explicit f…

Induced log-concavity of equivariant matroid invariants
Alice L. L. Gao, Ethan Y. H. Li, Matthew H. Y. Xie +2
Inspired by the notion of equivariant log-concavity, we introduce the concept of induced log-concavity for a sequence of representations of a finite group. For an equivariant matro…
