Abstract
Let \( {\mathbb{H}^n} \) be the Heisenberg group in \( {\mathbb{R}^{2n + 1 }} \) and D be a bracket generating left invariant distribution with a Lorentzian metric, which is a nondegenerate metric of index 1. In this paper, we first study the reachable sets by the time-like future directed curves. Second, we give a complete description of the Hamiltonian geodesics. Third, we compute the time-like conjugate locus of the origin.
