Mugur Acu - Some preserving properties of certain integral operators

Abstract: In this article we show that the class of uniform starlike
functions with negative coefficients and the class of uniform
convex functions with negative coefficients are preserved by the
Alexander integral operator and the class of uniform convex
functions with negative coefficients is preserved by the Bernardi
integral operator.
