International Journal of Mathematics and Mathematical Sciences, 1983, vol. 6, 1-7

Abstract:

A class T k of analytic functions in the unit disc is defined in which the concept of close-to-convexity is generalized. A necessary condition for a function f to belong to T k , raduis of convexity problem and a coefficient result are solved in this paper.
