A Littlewood-Richardson type rule for row-strict quasisymmetric Schur functions [PDF]
Discrete Mathematics & Theoretical Computer Science, 2011 We establish several properties of an algorithm defined by Mason and Remmel (2010) which inserts a positive integer into a row-strict composition tableau.

Journal of High Energy Physics, 2019 We compute general expressions for two types of three-point functions of (semi-)short multiplets in four-dimensional N = 2 $$ \mathcal{N}=2 $$ superconformal field theories.

Transactions of the American Mathematical Society, 1994 A new family of symmetric functions is considered. These functions are analogous to the classical Schur functions, but depend on an integer modulus p ⩾

Schur Functions and Inner Functions on the Bidisc
Computational Methods and Function Theory, 2022 We study representations of inner functions on the bidisc from a fractional linear transformation point of view, and provide sufficient conditions, in terms of colligation matrices, for the existence of two-variable inner functions. Here the sufficient conditions are not necessary in general, and we prove a weak converse for rational inner functions ...

Journal of Combinatorial Theory, Series A, 1997 The purpose of this paper is to give a bijective proof of the following identity for Schur functions. This identity arose in the work of \textit{M. Ciucu} [Enumeration of perfect matchings in graphs with reflective symmetry, preprint, 1995] and was stated as a conjecture there.

Vertex algebra of extended operators in 4d N=2 superconformal field theories. Part I
Journal of High Energy Physics, 2023 We construct a class of extended operators in the cohomology of a pair of twisted Schur supercharges of 4d N $$ \mathcal{N} $$ =2 SCFTs. The extended operators are constructed from the local operators in this cohomology — the Schur operators — by a ...

The ABC's of affine Grassmannians and Hall-Littlewood polynomials [PDF]
Discrete Mathematics & Theoretical Computer Science, 2012 We give a new description of the Pieri rule for $k$-Schur functions using the Bruhat order on the affine type-$A$ Weyl group. In doing so, we prove a new combinatorial formula for representatives of the Schubert classes for the cohomology of affine ...

Schur-Convexity of Two Types of One-Parameter Mean Values in n Variables
Journal of Inequalities and Applications, 2007 We establish Schur-convexities of two types of one-parameter mean values in n variables. As applications, Schur-convexities of some well-known functions involving the complete elementary symmetric functions are obtained.

Quasisymmetric Schur functions and modules of the $0$-Hecke algebra [PDF]
Discrete Mathematics & Theoretical Computer Science, 2014 We define a $0$-Hecke action on composition tableaux, and then use it to derive $0$-Hecke modules whose quasisymmetric characteristic is a quasisymmetric Schur function.
