Web31 de mai. de 2011 · Let g be an analytic function on the unit disc and consider the integration operator of the form {T_g f (z) = \int_0^z fg'\,d\zeta}. We derive estimates for the essential and weak essential norms of T g on the spaces H p and BMOA. In particular, on H 1 and BMOA the operator T g is weakly compact if and only if it is compact. WebOperator-norm limits of nite-rank operators are compact 1.

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.
