Laplacians and Sub-Laplacians [PDF]

open access: possible, 2010
We have seen in the previous chapters how an elliptic operator can be associated in a natural way with a geometric Riemannian structure. In a similar way sub-elliptic operators arise from similar structures, called sub-Riemannian structures, which will be discussed next. References for sub-Riemannian manifolds are [27] and [92].

Dirac Laplacian and Connection Laplacian [PDF]

open access: possible, 1993
We discuss the general Bochner identity which gives an expression of the Dirac Laplacian A 2 in terms of the connection Laplacian D*D and certain bundle ...

On the spectrum of the Laplacian

Mathematische Annalen, 2013
In this article we prove a generalization of Weyl’s criterion for the essential spectrum of a self-adjoint operator on a Hilbert space. We then apply this criterion to the Laplacian on functions over open manifolds and get new results for its essential spectrum.
