The $q$ -Poincaré sum and separability in a Coxeter group

Ben Adenbaum, Darij Grinberg

Given a finite Coxeter group $W$ and an element $q$ of a commutative ring $k$ , we define the element $L_{q} := \sum_{w \in W} q^{ℓ (w)} w$ of its group…

Invariance of rowmotion for variants of the Tamari lattice

Ben Adenbaum, Emily Barnard, Cesar Ceballos +6

We show that the rowmotion operator from dynamical algebraic combinatorics behaves the same on all alt $ν$ -Tamari lattices for a fixed lattice path $ν$ . We use this invariance of r…

Enumerating Pattern Avoiding Parking Functions

Ben Adenbaum

In this paper, we complete the enumeration of the number of parking functions of length $n$ avoiding, in the sense defined by Qiu and Remmel, a permutation of length 3, answering s…
