Abstract
We announce the construction of a deformation of the Dirac operator on a compact spin manifold into a hypoelliptic Dirac operator on the total space of the tangent space. This construction gives an analogue for the Dirac operator of a related deformation we already gave for the de Rham complex. For simplicity, we only explain the construction in the case of complex manifolds. We define hypoelliptic Quillen metrics, which we compare to the classical Quillen metrics.
