Cauchy Integrals Method in the Study of Perturbations of Operators
We show that functions which are analytic on the open unit disc and fulfil the Hölder condition of order r there, where r lies in the interval (0,1), are operator Hölder of order r on the set of all linear contractions on a Hilbert space. Further, it is known that analytic Lipschitz functions on th...
