A Normalization Formula for the Jack Polynomials in Superspace and an Identity on Partitions

Luc Lapointe, Yvan Le Borgne, Philippe Nadeau

Abstract


We prove a conjecture of Desrosiers, Lapointe and Mathieu giving a closed form formula for the norm of the Jack polynomials in superspace with respect to a certain scalar product. The proof is mainly combinatorial and relies on the explicit expression in terms of admissible tableaux of the non-symmetric Jack polynomials. In the final step of the proof appears an identity on weighted sums of partitions that we demonstrate using the methods of Gessel-Viennot.
