The magnetic Laplacian acting on discrete cusps

Sylvain Golénia, Françoise Truc

We introduce the notion of discrete cusp for a weighted graph. In this context, we provethat the form-domain of the magnetic Laplacian and that of thenon-magnetic Laplacian can be…

The spectrum of Schrödinger operators and Hodge Laplacians on conformally cusp manifolds

Sylvain Golénia, Sergiu Moroianu

We describe the spectrum of the -form Laplacian on conformally cusp Riemannian manifolds. The essential spectrum is shown to vanish precisely when the and de Rham coho…
