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 . We also derive sharp upper and lower bou…

Bohr type inequality for {C}esáro and {B}ernardi integral operator on simply connected domain
Vasudevarao Allu, Nirupam Ghosh
In this article, we study the Bohr type inequality for {C}esáro operator and {B}ernardi integral operator acting on the space of analytic functions defined on a simply connected do…
Coefficient Estimates for Certain Subclass of Analytic Functions Defined by Subordination
Nirupam Ghosh, A. Vasudevarao
In this article we determine the coefficient bounds for functions in certain subclasses of analytic functions defined by subordination which are related to the well-known classes o…
