On Bohr Radius of Certain Analytic Functions with Negative Coefficients

Abstract

The key purpose of this paper is to investigate the Bohr radius for several subclasses of analytic functions with negative coefficients. Our investigation with the Bohr radius correlates with the classes of generalized Janowski type functions. Under this novel strategy, we develop Bohr’s phenomenon for a generalized class associated with q-functions having q ∈ (0, 1). In the applications viewpoint, our consequences have shown the applicability in the class inaugurated by Bessel functions.
