Convolution and coefficient problems for multivalent functions defined by subordination [QA1].

Abstract

Dalam Bab 1, kelas-kelas teritlak bak-bintang multivalen, cembung, hampir-cembung dan kuasi-cembung diperkenalkan. Kelas-kelas tersebut memberi kaedah penyatuan untuk pelbagai subkelas yang diketahui sebelum ini. In Chapter 1, the general classes of multi-valent starlike, convex, close-to-convex and quasi-convex functions are introduced. These classes provide a unified treatment to various known subclasses.
