On certain subclasses of multivalently meromorphic close-to-convex maps
Let Mₚ denote the class of functions f of the form , p a positive integer, in the unit disk E = |z| < 1, f being regular in 0 < |z| < 1. Let , α < 1, where . Results on are derived by proving more general results on differential subordination. These results reduce, by putting p =1, to the recent results of Al-Amiri and Mocanu.

On classes of uniformly starlike functions
We geometrically define subclasses of starlike functions related to the class of uniformly starlike functions introduced by A. W. Goodman in 1991. We give an analytic characterization of these classes, some radius properties, and examples of functions in these classes. Our classes generalize the class of uniformly starlike functions, and many results of Goodman are special cases of our results.

On coefficient inequalities in the Carathéodory class of functions
Some inequalities are proved for coefficients of functions in the class P(α), where α ∈ [0,1), of functions with real part greater than α. In particular, new inequalities for coefficients in the Carathéodory class P(0) are given.
