Some properties of a new subclass of analytic univalent functions defined by multiplier transformation

, 2019
The purpose of the present paper is to study the integral operator of the form ∫z0{Inμf(t)t}δdt where $f$ belongs to the subclass $C(n,\alpha,\beta, \mu)$ and $\delta$ is a real number.

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.
