Abstract
In this paper we study coefficient problems in some subclasses of close-to-convex functions. More precisely, we determine the upper bounds of the third and the fourth logarithmic coefficients, $\gamma_3$ and $\gamma_4$, for functions in some subclasses of analytic and univalent functions in the unit disc $\mathbb{D}$. In our research we use not only classical results, but also recent results obtained by Efraimidis.
