摘要：
Our main result is a characterization of g for which the operator S(g)(f)(z) = integral(z)(0)f'(w) g(w) dw is bounded below on the Bloch space. We point out analogous results for the Hardy space H(2) and the Bergman spaces A(p) for 1 <= p < infinity. We also show the companion operator T(g)(f)(z) = integral(z)(0)f(w)g'(w) dw is never bounded below on H(2), Bloch, nor BMOA, but may be bounded below on A(p).
