A k-tableau characterization of k-Schur functions
Luc Lapointe, Jennifer Morse
We study k-Schur functions characterized by k-tableaux, proving combinatorial properties such as a k-Pieri rule and a k-conjugation. This new approach relies on developing the theo…

Quantum cohomology and the k-Schur basis
L. Lapointe, J. Morse
We prove that structure constants related to Hecke algebras at roots of unity are special cases of k-Littlewood-Richardson coefficients associated to a product of k-Schur functions…
