An identity involving $h$ -polynomials of poset associahedra and type B Narayana polynomials

Son Nguyen

For any finite connected poset $P$ , Galashin introduced a simple convex $(∣ P ∣ - 2)$ -dimensional polytope $A (P)$ called the poset associahedron. Let $P$ be a poset with a pr…

Bulgarian Solitaire: A new representation for depth generating functions

A. J. Harris, Son Nguyen

Bulgarian Solitaire is an interesting self-map on the set of integer partitions of a fixed number $n$ . As a finite dynamical system, its long-term behavior is well-understood, havi…
