Deficit and $(q,t)$-symmetry in triangular partitions

Combinatorics 2026-04-02 v1

Abstract

We study the (q,t)(q,t)-enumeration of triangular Dyck paths considered by Bergeron and Mazin. To do so, we introduce the notion of triangular and sim-sym tableaux and the deficit statistic which is a new interpretation of the dinv. We use it to obtain new results and proofs on triangular 22-partitions and an interesting conjecture for a certain lattice interval (q,t,r)(q,t,r)-enumeration.
