Sharp Bohr-Type inequalities for certain classes of close-to-convex functions

Complex Variables 2026-05-25 v1

Abstract

In this article, we determine the Rogosinski radii for certain subclasses of close-to-convex functions defined on open unit disc D={zC:z<1}\mathbb{D}= \{z \in \mathbb{C}: |z| < 1\}. Furthermore, we establish improved versions of the classical Bohr inequality and the Bohr-Rogosinski inequality pertaining to these subclasses. We demonstrate that all results derived in the study are sharp.
