| Keywords:Hankel determinant bounded turning functions four-leaf-type |
| Abstract: |
| In the paper, a family of bounded turning functions involving a four-leaf-type domain is studied in the unit disk. The goal of the study is to explore the bounds of second and the third Hankel determinant for functions in the class. All of obtained bounds have been sharp. |
