### Coefficient Conditions for Harmonic Close-to-Convex Functions

Toshio Hayami

#### Abstract

New sufficient conditions, concerned with the coefficients of harmonic functions $f(z)=h(z)+\overline{g(z)}$ in the open unit disk $\mathrm{\Bbb U}$ normalized by $f(0)=h(0)={h}^{\prime }(0)-1=0$, for $f(z)$ to be harmonic close-to-convex functions are discussed. Furthermore, several illustrative examples and the image domains of harmonic close-to-convex functions satisfying the obtained conditions are enumerated.
