Abstract
A class consisting of analytic functions
in the unit disc
satisfies a Bohr phenomenon if there exists an
such that
for every function
, and
. The largest radius
is the Bohr radius and the inequality
is Bohr inequality for the class
, where ‘d’ is the Euclidean distance. In this paper, we prove sharp refinement of the Bohr–Rogosinski inequality for certain classes of harmonic mappings.
