The Weyl asymptotic formula by the method of Tulovskiĭ and Shubin

Let A be a pseudodifferential operator on N whose Weyl symbol a is a strictly positive smooth function on W = N × N such that | α a | C α a 1 - ϱ for some ϱ>0 and all |α|>0, α a is bounded for large |α|, and l i m w a ( w ) = . Such an operator A is essentially selfadjoint, bounded from below, and its spectrum is discrete. The remainder term in the Weyl asymptotic formula for the distribution of the eigenvalues of A is estimated. This is done by applying the method of approximate spectral projectors of Tulovskiĭ and Shubin. ...
