Abstract

Abstract

We present some applications of Jack-Fukui-Sakaguchi Lemma which become sufficient criteria for a function to be in the class of strongly starlike, strongly close-to-convex or in the other classes.
- Bazilevič function /
- close-to-convex functions /
- convex functions /
- starlike functions
