Lascoux expansion of the product of a Lascoux and a stable Grothendieck
Gidon Orelowitz, Tianyi Yu
This paper gives a tableau formula for expanding the product of a Lascoux polynomial and a stable Grothendieck polynomial into Lascoux polynomials. Lascoux and stable Grothendieck…
Combinatorics and Representation Theory of Special Cases of Chern Plethysm
Nathaniel Libman, Gidon Orelowitz
Chern plethysm (introduced by Billey, Rhoades, and Tewari) is a geometric way to produce Schur positive symmetric polynomials. We present combinatorial interpretations for the Schu…
Approximate counting of standard set-valued tableaux
Reuven Hodges, Gidon Orelowitz
We present a randomized algorithm for generating standard set-valued tableaux by extending the Green-Nijenhuis-Wilf hook walk algorithm. In the case of asymptotically rank two part…
Newell-Littlewood numbers III: eigencones and GIT-semigroups
Shiliang Gao, Gidon Orelowitz, Nicolas Ressayre +1
The Newell-Littlewood numbers are tensor product multiplicities of Weyl modules for the classical groups in the stable range. Littlewood-Richardson coefficients form a special case…
The Kostka semigroup and its Hilbert basis
Shiliang Gao, Joshua Kiers, Gidon Orelowitz +1
The Kostka semigroup consists of pairs of partitions with at most r parts that have positive Kostka coefficient. For this semigroup, Hilbert basis membership is an NP-complete prob…
Multiplicity-free skew Schur polynomials
Shiliang Gao, Reuven Hodges, Gidon Orelowitz
We provide a non-recursive, combinatorial classification of multiplicity-free skew Schur polynomials. These polynomials are , and , characters of the skew Schur modules…
Newell-Littlewood numbers II: extended Horn inequalities
Shiliang Gao, Gidon Orelowitz, Alexander Yong
The Newell-Littlewood numbers are tensor product multiplicities of Weyl modules for classical Lie groups, in the stable limit. For which triples of partitions …
Super-Catalan Numbers of the Third and Fourth Kind
Irina Gheorghiciuc, Gidon Orelowitz
The Super-Catalan numbers are a generalization of the Catalan numbers defined as . It is an open problem to find a combinatorial interpreta…
Newell-Littlewood numbers
Shiliang Gao, Gidon Orelowitz, Alexander Yong
The Newell-Littlewood numbers are defined in terms of their celebrated cousins, the Littlewood-Richardson coefficients. Both arise as tensor product multiplicities for a classical…
Maximizing the Edelman-Greene statistic
Gidon Orelowitz
The of S. Billey-B. Pawlowski measures the "shortness" of the Schur expansion of a Stanley symmetric function. We show that the maximum value of…
