Bohr phenomenon for the special family of analytic functions and harmonic mappings

In this paper we obtain the sharp Bohr radius for a family of bounded analytic functions $\mathcal B'$ and for the family of sense-preserving $\mathrm{K}$-quasiconformal harmonic mappings of the form $f = h + \overline g$, where $h\in \mathcal B'$.
