Abstract

Mathematics Physical Sciences Science & Technology
We introduce the subclass T-p( j,lambda,alpha,n) of p-valent functions with negative coffcients by using the diffierential operator D-n which was considered by G. St. Salagean. Coffcient inequalities, distortion theorms, closure theorms, and some properties in- volving the modified Hadamard product of several functions belonging to the class are obtained.
