Abstract

In this chapter we shall describe the parametrix approximation of e-tA, A a positive elliptic global polynomial differential system, which will then be used, through Karamata’s Tauberian theorem (proved in Section 6.2), to compute the leading coefficient of the asymptotic behavior for large eigenvalues of the spectral counting function, in terms of the symbol of the system.
