In this paper, we study the spectrum of the operator (0.1) on and a pseudodifferential operator of order strictly smaller than M. We prove that most of its eigenvalues admit the asymptotic expansion (0.2) Z is a function (symbol) and (the dual lattice of Gamma).

Abstract
In this paper, we study the spectrum of the operator (0.1) on and a pseudodifferential operator of order strictly smaller than M. We prove that most of its eigenvalues admit the asymptotic expansion (0.2) Z is a function (symbol) and (the dual lattice of Gamma).File in questo prodotto:
