Fundamental quasisymmetric functions in superspace
Susanna Fishel, Jessica Gatica, Luc Lapointe +1
The fundamental quasisymmetric functions in superspace are a generalization of the fundamental quasisymmetric functions involving anticommuting variables. We obtain the action of t…

Hopf algebra structure of symmetric and quasisymmetric functions in superspace
Susanna Fishel, Luc Lapointe, Maria Elena Pinto
We show that the ring of symmetric functions in superspace is a cocommutative and self-dual Hopf algebra. We provide formulas for the action of the coproduct and the antipode on va…

Charge on tableaux and the poset of k-shapes
Luc Lapointe, Maria Elena Pinto
A poset on a certain class of partitions known as k-shapes was recently introduced to provide a combinatorial rule for the expansion of a (k-1)-Schur functions into k-Schur functio…
