followed by the formal definition of the Hopf algebra of quasisymmetric functions in 1984 by …

[HTML][HTML] Modules of the 0-Hecke algebra and quasisymmetric Schur functions

VV Tewari, SJ van Willigenburg - Advances in Mathematics, 2015 - Elsevier
We begin by deriving an action of the 0-Hecke algebra on standard reverse composition
tableaux and use it to discover 0-Hecke modules whose quasisymmetric characteristics are …

[HTML][HTML] Dual immaculate quasisymmetric functions expand positively into Young quasisymmetric Schur functions

EE Allen, J Hallam, SK Mason - Journal of Combinatorial Theory, Series A, 2018 - Elsevier
We describe a combinatorial formula for the coefficients when the dual immaculate
quasisymmetric functions are decomposed into Young quasisymmetric Schur functions. We …

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 …

R matrix for generalized quantum group of type A

JH Kwon, J Yu - Journal of Algebra, 2021 - Elsevier
The generalized quantum group U (ϵ) of type A is an affine analogue of quantum group
associated to a general linear Lie superalgebra gl M| N. We prove that there exists a unique …

Canonical bases for the quantum enveloping algebra of gl (m| 1) and its modules

S Clark - arXiv preprint arXiv:1605.04266, 2016 - arxiv.org
We construct a crystal basis for the negative half of the quantum group U associated to the
standard super Cartan datum of gl (m| 1), which is compatible with known crystals on Kac …

Superization and (q, t)-specialization in combinatorial Hopf algebras

JC Novelli, JY Thibon - arXiv preprint arXiv:0803.1816, 2008 - arxiv.org
We extend a classical construction on symmetric functions, the superization process, to
several combinatorial Hopf algebras, and obtain analogs of the hook-content formula for the …

A Note on Jing and Li's type B Quasisymmetric Schur functions

E Kantarcı Oğuz - Annals of Combinatorics, 2019 - Springer
Abstract In 2015, Jing and Li defined type B quasisymmetric Schur functions and
conjectured that these functions have a positive, integral and unitriangular expansion into …

Rigidity for the Hopf algebra of quasi-symmetric functions

W Jia, Z Wang, H Yu - arXiv preprint arXiv:1712.06499, 2017 - arxiv.org
We investigate the rigidity for the Hopf algebra ${\rm QSym} $ of quasisymmetric functions
with respect to the monomial, the fundamental and the quasisymmetric Schur basis …

Quasisymmetric (k, l)-Hook Schur Functions

SK Mason, E Niese - Annals of Combinatorics, 2018 - Springer
We introduce a quasisymmetric generalization of Berele and Regev's hook Schur functions
and prove that these new quasisymmetric hook Schur functions decompose the hook Schur …
