Logarithmic Inverse Coefficients and Moduli Differences of Janowski Class

Chayani Dhara, Nirupam Ghosh

In this paper, we study the sharp bounds of the first three logarithmic inverse coefficients for Janowski convex class $C (A, B)$ . We also derive sharp upper and lower bou…

Logarithmic Coefficients Problems of Geometric Subclass of Closed-to-convex Functions

Chayani Dhara, Nirupam Ghosh

For $I^\pm \geq 0$ , let $W (I^\pm)$ be the class of all analytic functions in the unit disk $D$ with normalization $f (0) = 0$ and $f^{'} (0) = 1$ that satisfy the relation…

On posinormality of weighted composition-differentiation operators on $H^{2} (D)$

Gour Hait, Sarita Ojha, Nirupam Ghosh +1

In this article, the posinormality and coposinormality of weighted composition-differentiation operators on Hardy space $H^{2} (D)$ are investigated. It is observed that whil…
