MacMahon’s statistics on higher-dimensional partitions

open access: yesForum of Mathematics, Sigma, 2023
We study some combinatorial properties of higher-dimensional partitions which generalize plane partitions. We present a natural bijection between d-dimensional partitions and d-dimensional arrays of nonnegative integers.

New proofs of Schur-concavity for a class of symmetric functions

open access: yesJournal of Inequalities and Applications, 2012
By properties of the Schur-convex function, Schur-concavity for a class of symmetric functions is simply proved uniform.2000 Mathematics Subject Classification: Primary 26D15; 05E05; 26B25.

Positivity of Schur function expansions of Thom polynomials [PDF]

open access: yes, 2006
Combining the Kazarian approach to Thom polynomials via classifying spaces of singularities with the Fulton-Lazarsfeld theory of numerical positivity for ample vector bundles, we show that the coefficients of various Schur function expansions of the Thom

An Analytic Formula for the A_2 Jack Polynomials [PDF]

open access: yes, 2007
In this letter I shall review my joint results with Vadim Kuznetsov and Evgeny Sklyanin [Indag. Math. 14 (2003), 451-482, math.CA/0306242] on separation of variables for the $A_n$ Jack polynomials.

Some Combinatorial Properties of Hook Lengths, Contents, and Parts of Partitions [PDF]

open access: yes, 2009
This paper proves a generalization of a conjecture of Guoniu Han, inspired originally by an identity of Nekrasov and Okounkov. The main result states that certain sums over partitions p of n, involving symmetric functions of the squares of the hook ...

The Rogers-Ramanujan identities, the finite general linear groups, and the Hall-Littlewood polynomials [PDF]

open access: yes, 1997
We connect Gordon's generalization of the Rogers-Ramanujan identities with the Hall-Littlewood polynomials and with generating functions which arise in a probabilistic setting in the finite general linear groups.

In vitro antimicrobial activity of a gel containing antimicrobial peptide AMP2041, chlorhexidine digluconate and Tris‐EDTA on clinical isolates of Pseudomonas aeruginosa from canine otitis

open access: yesVeterinary Dermatology, Volume 27, Issue 5, Page 391-e98, October 2016., 2016
Background– Pseudomonas aeruginosa (PA) may cause suppurative otitis externa with severe inflammation and ulceration in dogs. Multidrug resistance is commonly reported for this organism, creating a difficult therapeutic challenge. Objective– The aim of this study was to evaluate the in vitro antimicrobial activity of a gel containing 0.5 µg/mL of ...

HALF-SPACE MACDONALD PROCESSES

open access: yesForum of Mathematics, Pi, 2020
Macdonald processes are measures on sequences of integer partitions built using the Cauchy summation identity for Macdonald symmetric functions. These measures are a useful tool to uncover the integrability of many probabilistic systems, including the ...
