Inverse Kazhdan--Lusztig polynomials of fan matroids
Alice L. L. Gao, Ya-Xing Li, Yun Li
The inverse Kazhdan--Lusztig polynomial of a matroid was introduced by Gao and Xie, and the inverse -polynomial of a matroid was introduced by Ferroni, Matherne, Stevens, and Ve…

Equivariant inverse -polynomials of matroids
Alice L. L. Gao, Yun Li, Matthew H. Y. Xie
Motivated by the notion of the inverse -polynomial introduced by Ferroni, Matherne, Stevens, and Vecchi, we study the equivariant inverse -polynomial of a matroid equipped wi…

Equivariant inverse Kazhdan--Lusztig polynomials of thagomizer matroids
Alice L. L. Gao, Yun Li, Matthew H. Y. Xie
In this paper, we focus on the equivariant inverse Kazhdan--Lusztig polynomials of thagomizer matroids, a natural family of graphic matroids associated with the complete tripartite…
