This volume looks at the spectral theory of global hypoelliptic pseudodifferential operators in Rn and the asymptotic estimate of the eigenvalue distribution function N of a hypoelliptic differential operator with polynomial coefficients in Rn.

This volume looks at the spectral theory of global hypoelliptic pseudodifferential operators in Rn and the asymptotic estimate of the eigenvalue distribution function N of a hypoelliptic differential operator with polynomial coefficients in Rn. The first section introduces the pseudodifferential calculus with respect to a multi-quasi-elliptic weight; while the second part computes the asymptotic expansion of N for a multi-quasi-elliptic differential operator with polynomial coefficients. This is achieved by computing the asymptotic expansion of the Weyl term V. In this way, results are obtained with respect to a refinement of the asymptotic formula and the class of symbols considered.
