Second Hankel Determinant Problem for k-bi-starlike Functions

Halit Orhan, Evrim Toklu, Ekrem Kadioglu


In the present work, we introduce k-bi-starlike functions defined by making use of the Sălăgean derivative operator. Upper bounds on the second Hankel determinant for k-bi-starlike functions are investigated. Relevant connections of the results presented here with various well-known results are briefly indicated.
