On sandwich theorems for certain subclasses of non-Bazilevič functions involving Cho-Kim transformation \(\|\). (English) Zbl 1138.30307

Summary: The purpose of this present article is to derive some subordination and superordination results involving Cho-Kim transformation for certain normalized analytic functions in the open unit disk. Relevant connections of the results, which are presented in the article, with various known results are pointed out.
