Semiclassical Distribution of Eigenvalues for Elliptic Operators with Holder Continuous Coefficients, Part II: Critical Case
Résumé
We consider a version of the Weyl formula describing the asymptotic behaviour of the counting function of eigenvalues in the semiclassical approximation for self-adjoint elliptic differential operators under weak regularity hypotheses. Our aim is to treat Hölder continuous coefficients and to investigate the case of critical energy velues as well.
