Characterization of queer supercrystals

M Gillespie, G Hawkes, W Poh, A Schilling - Journal of Combinatorial …, 2020 - Elsevier
We provide a characterization of the crystal bases for the quantum queer superalgebra
recently introduced by Grantcharov et al. This characterization is a combination of local …

Combinatorial Howe duality of symplectic type

T Heo, JH Kwon - Journal of Algebra, 2022 - Elsevier
We give a new combinatorial interpretation of Howe dual pairs of the form (g, Sp 2 ℓ), where
g is a Lie (super) algebra of classical type. This is done by establishing a symplectic …

On the Harish-Chandra homomorphism for quantum superalgebras

Y Luo, Y Wang, Y Ye - Communications in Mathematical Physics, 2022 - Springer
In this paper, we introduce the Harish-Chandra homomorphism for the quantum
superalgebra U q (g) associated with a simple basic Lie superalgebra g and give an explicit …

Flagged Littlewood-Richardson tableaux and branching rule for classical groups

IS Jang, JH Kwon - Journal of Combinatorial Theory, Series A, 2021 - Elsevier
We give a new formula for the branching rule from GL n to O n generalizing the Littlewood's
restriction formula. The formula is given in terms of Littlewood-Richardson tableaux with …

Crystal base of the negative half of the quantum superalgebra Uq (gl (m| n))

IS Jang, JH Kwon, A Uruno - Journal of Algebra, 2023 - Elsevier
We construct a crystal base of U q (gl (m| n))−, the negative half of the quantum
superalgebra U q (gl (m| n)). We give a combinatorial description of the associated crystal B …

Super duality and crystal bases for quantum ortho-symplectic superalgebras

JH Kwon - International Mathematics Research Notices, 2015 - academic.oup.com
We introduce a semisimple tensor category of modules over a quantum ortho-symplectic
superalgebra. It is a natural counterpart of the category of finitely dominated integrable …

Combinatorial extension of stable branching rules for classical groups

JH Kwon - Transactions of the American Mathematical Society, 2018 - ams.org
We give new combinatorial formulas for decomposition of the tensor product of integrable
highest weight modules over the classical Lie algebras of types $ B, C, D $, and the …

[HTML][HTML] Lusztig data of Kashiwara–Nakashima tableaux in types B and C

JH Kwon - Journal of Algebra, 2018 - Elsevier
We provide an explicit combinatorial description of the embedding of the crystal of
Kashiwara–Nakashima tableaux in types B and C into that of i-Lusztig data associated to a …

Lusztig data of Kashiwara-Nakashima tableaux in type D

IS Jang, JH Kwon - Algebras and Representation Theory, 2021 - Springer
We describe the embedding from the crystal of Kashiwara-Nakashima tableaux in type D of
an arbitrary shape into that of i-Lusztig data associated to a family of reduced expressions i …
