A Connection between Basic Univalence Criteria

Abstract EN

We obtain a sufficient condition for the analyticity and the univalence of a class of functions defined by an integral operator.

The well-known univalence criteria of Alexander, Noshiro-Warschawski, Nehari, Goluzin, Ozaki-Nunokawa, Becker, and Lewandowski would follow upon specializing the functions and the parameters involved in the main result.

The results obtained not only reduce to those earlier works, but they also extend the previous results.
