https://earthlinepublishers.com/index.php/ejms/article/view/448
<p>In the present article, we define a new family for holomorphic functions (so-called Bazilevic-Sakaguchi type functions) and determinate strong differential subordination and superordination results for these new functions by investigating certain suitable classes of admissible functions. These results are applied to obtain strong differential sandwich results.</p>Abbas Kareem WanasNajah Ali Jiben Al-Ziadi

https://earthlinepublishers.com/index.php/ejms/article/view/449
<p>In this paper, we introduce a new class $K_{q}(\alpha), \quad 0<\alpha \leq1, \quad 0<q<1, $ of normalized analytic functions $f $ such that $\big|\arg\frac{D_qf(z)}{D_qg(z)}\big| \leq \alpha \frac{\pi}{2},$ where $g$ is convex univalent in $E= \{z: |z|<1\} $ and $D_qf $ is the $q$-derivative of $f $ defined as:<br>$$D_qf(z)= \frac{f(z)-f(qz)}{(1-q)z}, \quad z\neq0\quad D_qf(0)= f^{\prime}(0). $$<br>The problem of growth of the Hankel determinant $H_n(k) $ for the class $K_q(\alpha) $ is investigated. Some known interesting results are pointed out as applications of the main results.</p>Khalida Inayat NoorMuhammad Aslam Noor

https://earthlinepublishers.com/index.php/ejms/article/view/453
<p>In current effort, by making use of the principle of subordination, we introduce and study a new family of holomorphic and bi-univalent functions which are defined in open unit disk and solve Fekete-SzegĂ¶ problem for functions which belong to this family.</p>Abbas Kareem WanasHaeder Younis Althoby

https://earthlinepublishers.com/index.php/ejms/article/view/454
<p>The primary motivation behind this paper is to present a brief overview of the bipolar complex intuitionistic fuzzy sets (in short BCIFS) which is an extension of bipolar intuitionistic fuzzy set theory.</p>Abdallah Al-Husban
