Open boundary Quantum Knizhnik-Zamolodchikov equation and the weighted enumeration of Plane Partitions with symmetries

Abstract

We propose new conjectures relating sum rules for the polynomial solution of the qKZ equation with open (reflecting) boundaries as a function of the quantum parameter $q$ and the $\tau$-enumeration of Plane Partitions with specific symmetries, with $\tau =-(q+q^{-1})$. We also find a conjectural relation à la Razumov-Stroganov between the $\tau \to 0$ limit of the qKZ solution and refined numbers of Totally Symmetric Self Complementary Plane Partitions.
