Reciprocal Classes Of P-Valently Spirallike And P-Valently Robertson Functions

Abstract

For p-valently spirallike and p-valently Robertson functions in the open unit disk U, reciprocal classes S-p(alpha, beta), and C-p(alpha, beta) are introduced. The object of the present paper is to discuss some interesting properties for functions f(z) belonging to the classes S-p(alpha, beta) and C-p(alpha, beta).
