Certain applications of subordination associated with neighborhoods

Abstract

In this paper we introduce the classes $T^p _n (lambda, mu, A, B)$and $K^p _n (lambda, mu, A, B)$, and derive coefficient bounds and distortion inequalities for functions belonging to the class T%(,A,B). Further, we make use of the $(n, delta)$-neighborhoods of functions in both classes $T^p _n (lambda, mu, A, B)$ and $K^p _n (lambda, mu, A, B)$
