    There is given a general answer for two questions posed by \textit{L. D. Fadeev} and \textit{B. S. Pavlov} (cf. Zap Nauchn. Sem. Leningr. Otd. Mat. Inst. Steklova 81, 85-87 (1978; Zbl 0486.47001)) concerning estimations for some analytic functions defined in an open disc of the complex plane and with values in the algebra of all compact operators acting in a separable Hilbert space.
