These results are applied to obtain strong differential sandwich results.</p>2022-01-10T00:00:00+00:00Copyright (c) https://earthlinepublishers.com/index.php/ejms/article/view/449Hankel Determinant Problem for q-strongly Close-to-Convex Functions2022-01-11T16:12:50+00:00Khalida Inayat Noorkhalidan@gmail.comMuhammad Aslam Noornoormaslam@gmail.com<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>2022-01-11T00:00:00+00:00Copyright (c) https://earthlinepublishers.com/index.php/ejms/article/view/451Generating Functions of Binary Products of Tribonacci and Tribonacci Lucas Polynomials and Special Numbers2022-01-16T15:55:59+00:00Hind Merzoukmerzoukhind07@gmail.comAli Boussayoudaboussayoud@yahoo.frKasi Viswanadh V.
