Flow Polytopes and the Space of Diagonal Harmonics [PDF]
Canadian Journal of Mathematics, 2019 AbstractA result of Haglund implies that the$(q,t)$-bigraded Hilbert series of the space of diagonal harmonics is a$(q,t)$-Ehrhart function of the flow polytope of a complete graph with netflow vector$(-n,1,\ldots ,1)$. We study the$(q,t)$-Ehrhart functions of flow polytopes of threshold graphs with arbitrary netflow vectors.

Standard fillings to parking functions [PDF]
Discrete Mathematics & Theoretical Computer Science, 2012 The Hilbert series of the Garsia-Haiman module can be written as a generating function of standard fillings of Ferrers diagrams. It is conjectured by Haglund and Loehr that the Hilbert series of the diagonal harmonics can be written as a generating ...

Sweep maps for lattice paths [PDF]
Discrete Mathematics & Theoretical Computer Science, 2014 Sweep maps are a family of maps on words that, while simple to define, are not yet known to be injective in general. This family subsumes many of the "zeta maps" that have arisen in the study of q,t-Catalan numbers in the course of relating the three ...

Polynomials and Parking Functions [PDF]
Discrete Mathematics & Theoretical Computer Science, 2012 In a 2010 paper Haglund, Morse, and Zabrocki studied the family of polynomials $\nabla C_{p1}\dots C_{pk}1$ , where $p=(p_1,\ldots,p_k)$ is a composition, $\nabla$ is the Bergeron-Garsia Macdonald operator and the $C_\alpha$ are certain slightly modified

A $q,t-$analogue of Narayana numbers [PDF]
Discrete Mathematics & Theoretical Computer Science, 2013 We study the statistics $\mathsf{area}$, $\mathsf{bounce}$ and $\mathsf{dinv}$ associated to polyominoes in a rectangular box $m$ times $n$. We show that the bi-statistics ($\mathsf{area}$,$\mathsf{bounce}$) and ($\mathsf{area}$,$\mathsf{dinv}$) give ...

Generalized Tesler matrices, virtual Hilbert series, and Macdonald polynomial operators [PDF]
Discrete Mathematics & Theoretical Computer Science, 2015 We generalize previous definitions of Tesler matrices to allow negative matrix entries and non-positive hook sums. Our main result is an algebraic interpretation of a certain weighted sum over these matrices.

Frontiers in Earth Science, 2022 The filtering procedure is usually mandatory for modeling mean dynamic topography (MDT) when a geodetic approach based on the Mean Sea Surface (MSS) and the Global Geopotential Model (GGM) is used.
