Paolo Boggiatto, Ernesto Buzano. This book concerns the spectral theory of global hypoelliptic pseudodifferential operators in Rn and the asymptotic estimate of the eigenvalue distribution function N(l) of a hypoelliptic differential operator with polynomial coefficients in Rn. In the first part of the book the pseudodifferential calculus with respect to a weight is introduced.
