PODESTA, Ricardo A.. Spectral properties of elliptic operators on bundles of -manifolds. Rev. Unión Mat. Argent. [online]. 2006, vol.47, n.1, pp. 135-149. ISSN 1669-9637.

We present some results on the spectral geometry of compact Riemannian manifolds having holonomy group isomorphic to , , for the Laplacian on mixed forms and for twisted Dirac operators.
