Soc.Published online 2019 Jan 14 Ali Ebadian, ٰVali Soltani Masih, and Shahram Najafzadeh Department of Mathematics, Faculty of Science, Payame Noor University, P. O. Box 19395-3697, Tehran, Iran Abstract : Let $\mathscr{B}_{p,n}^{\eta, \mu}\left(\alpha\right)$; $\left( \eta, \mu\in \mathbb{R}, n,p\in \mathbb{N}\right)$ denote all multivalent functions $f$ class in the unit disk $\mathbb{U}$ as $f(z)=z^p+\sum_{k=n+p}^{\infty}a_kz^k$ which satisfy: \[ \left| \left[ \frac{f'(z)}{pz^{p-1}}\right]^{\eta} \left[ \frac{z^p}{f(z)}\right] ^{\mu}-1\right| <1-\frac{\alpha}{p}; \quad \left( z\in \mathbb{U}, \: 0\leq \alpha
