Univalent Criteria for Locally Univalent Functions

期刊： SOUTHEAST ASIAN BULLETIN OF MATHEMATICS, 2021; 45 (3)

Let f be a locally univalent function in the unit disk D = {z : vertical bar z vertical bar < 1}. In this paper, by using Schwarzian derivatives of......

A Class of U-Ample I-Semigroups

期刊： SOUTHEAST ASIAN BULLETIN OF MATHEMATICS, 2021; 45 (3)

In this paper, we study U-ample I-semigroups and obtain its structure theorem. It is proved that a semigroup is a U-ample I-semigroup if and only if i......
