Some sufficient conditions for strongly starlikeness
We consider strongly starlikeness of order α of functions f(z)=z+an+1zn+1+⋯ which are analytic in the unit disc and satisfy the condition of the form |f′(z)(zf(z))1+μ−1|<λ, 0<μ<1, 0<λ<1.

disc and satisfy the condition of the form
|f′(z)(zf(z))1+μ−1|<λ, 0<μ<1, 0<λ<1. |
