Certain Conditions for Strongly Starlike and Strongly Convex Functions
Authors/Creators
Description
In the present paper, we investigate a differential subordination
involving multiplier transformation related to a sector in the
open unit disk E = {z : |z| < 1}. As special cases to our main
result, certain sufficient conditions for strongly starlike and strongly
convex functions are obtained.
