Cho, Nak Eun; Kwon, Oh Sang A class of integral operators preserving subordination and superordination. (English) Zbl 1200.30007 Bull. Malays. Math. Sci. Soc. (2) 33, No. 3, 429-437 (2010). Summary: The purpose of the present paper is to obtain subordination- and superordination-preserving properties for a class of integral operators defined on the space of normalized analytic functions in the open unit disk. We also consider sandwich-type theorems for these integral operators.
