摘要
In the present paper we study a majorization problem for a class of analytic functions of alpha-convex functions defined by subordination with respect to a given function phi. In a special case we obtain the majorization problem for the class M (alpha) of alpha-convex functions. Further, coefficient bounds for some majorized functions are estimated.
