Corollary. Iff e R [A, B), then so are~ (j) and fix (j). Proof: The operators «l»y (j) and O:r (/) given by (12) and (13) are just two examples that can be realized as convolutions under specified convex functions. Remark: A direct proof that «l»y preserves R [A, BJ was given by V. Kumar [14), using Jack's Lemma. Next we consider opertors that are convex combinations of expressions involving functions from the given classes. For f (z) = z + L, anzn analytic in U and t ~ 0, we define n=2 At (j) = (1- t) f (z) + tzf'(z), z e U.
