Bohr-Rogosinski Inequalities for Some Harmonic Functions
This article studies the Bohr phenomenon for certain subclasses of some complex harmonic functions subclass-es defined on the unit disk.Specifically,by employing subordination principle,coefficient inequality and growth theorem,the relations between the parameters of these harmonic functions subclasses and the Bohr-Rogosinski radii is established,and the corresponding Bohr-Rogosinski inequalities are given.All the Bohr-Rogosinski radii involved in this paper are optimal.
