Abstract
We propose an analytic torsion for the Rumin complex associated with generic rank
two distributions on closed 5-manifolds. This torsion behaves as expected with respect
to Poincaré duality and finite coverings. We establish anomaly formulas, expressing
the dependence on the sub-Riemannian metric and the 2-plane bundle in terms of
integrals over local quantities. For certain nilmanifolds, we are able to show that this
torsion coincides with the Ray–Singer analytic torsion, up to a constant.
