Stability analysis for the pseudo-Riemannian geodesic flows of step-two nilpotent Lie groups
Year: 2026
Type: article
Abstract: The present paper deals with the stability analysis for the geodesic flow of a step-two nilpotent Lie group equipped with a left-invariant pseudo-Riemannian metric. The Lie-Poisson equation is formulated using the so-called [Formula: see text]-mapping, a linear operator associated to the step-two nilpotent Lie algebras equipped with the induced scalar product. The stability of equilibrium points for the Hamilton equation is determined in terms of their Williamson types.
