Nilpotent orbits of sl(n,R) admit no Gibbs state
Jérémie Pierard de Maujouy, Guillaume Neuttiens
Gibbs states are probability distributions defined on Hamiltonian G-manifolds. They are parametrized by an open set of the Lie algebra g and arise as natural equilibrium states wit…

Nilpotent orbits of classical Lie algebras stable under negation
Guillaume Neuttiens, Jérémie Pierard de Maujouy
Gibbs states are probability distributions defined on Hamiltonian G-manifolds that are naturally parametrized by elements of the Lie algebra g. In this paper, we focus on a specifi…
