Chaotic subRiemannian geodesic flow in $J^2({\mathbb{R}}^2,\mathbb{R})$

Abstract

The space of $2$-jets of a real function of two real variables, denoted by $J^2({\mathbb{R}}^2,\mathbb{R})$, admits the structure of a metabelian Carnot group, so $J^2({\mathbb{R}}^2,\mathbb{R})$ has a normal abelian sub-group $\mathbb{A}$. As any sub-Riemannian manifold, $J^2({\mathbb{R}}^2,\mathbb{R})$ has an associated Hamiltonian geodesic flow. The Hamiltonian action of $\mathbb{A}$ on $T^{\ast }{J}^2({\mathbb{R}}^2,\mathbb{R})$ yields the reduced Hamiltonian $H_{\mu }$ on $T^{\ast }\mathcal{H}\simeq T^{\ast }(J^2({\mathbb{R}}^2,\mathbb{R})/\mathbb{A})$, where $H_{\mu }$ is a two-dimensional Euclidean space. The paper is devoted to proving that reduced Hamiltonian $H_{\mu }$ is non-integrable by meromorphic functions for some values of $\mu$. This result suggests the sub-Riemannian geodesic flow on $J^2({\mathbb{R}}^2,\mathbb{R})$ is not meromorphically integrable.
