On some coefficient estimates for a class of p-valent functions

In this paper, we consider a class of p-valent functions. For functions in this class we find sharp estimates for their first three coefficients. Upper bound for the second order Hankel determinant is also obtained.

Abstract

In this paper, we consider a class of p-valent functions. For functions in this class we find sharp estimates for their first three coefficients. Upper bound for the second order Hankel determinant is also obtained.
