Equivariant Chow functions and Wonderful Models in type A and B

Roberto Pagaria, Tommaso Scognamiglio

We prove a general inversion formula in the equivariant incidence algebras of geometric lattices that relates the equivariant Chow function with the equivariant super-reduced chara…

Leaving the Hall: explicit formulas for Negut operators

Michele D'Adderio, Giovanni Interdonato, Alessandro Iraci +1

Recent major breakthroughs in $q, t$ -combinatorics include the introduction of the Dyck path algebra $A_{q, t}$ by Carlsson and Mellit and of the Catalanimals by Blasiak et…

The Poincaré polynomial of the type B analogue of $M_{0, n + 1}$

Luis Ferroni, Roberto Pagaria, Lorenzo Vecchi

We establish formulas for the Poincaré polynomial of the type B analogue of the Deligne--Knudsen--Mumford moduli space of rational curves with $n$ marked points, providing type B c…
