Webof the NP operators belongs to a certain Schatten class. We then use the Weyl’s lemma, which asserts the ℓp-norm of eigenvalues is less than that of singular values, to derive decay rates of eigenvalues. The necessary condition in [3] is given in terms of the Sobolev norm of the integral kernel of the operator. It says WebOperator-norm limits of nite-rank operators are compact 1.
