Abstract

In this paper we study a Hamiltonian function on the cotangent bundle of the space of Riemannian metrics on a 3-manifold MM and prove the orbits of the constrained Hamiltonian dynamical system correspond to G2G_2-manifolds foliated by hypersurfaces diffeomorphic to M×SO(3)M\times \mathrm{SO}(3).
