On the class of analytic functions defined by Robertson associated with nephroid domain

The primary focus of this article is to explore a novel subclass, denoted as GNGN, of analytic functions. These functions exhibit starlike properties concerning a boundary point within a nephroid domain. The author obtains representation ...

Notes on starlike log-harmonic functions of order α

, 2013
For log-harmonic functions f(z) = zh(z)g(z) in the open unit disk U, two subclasses H*LH(α) and G*LH(α) of S*LH(α) consisting of all starlike log-harmonic functions of order α (0 ≤ α < 1) are considered. The object of the present paper is to discuss some

Multivalued Sakaguchi functions

, 2007
Let A be the class of functions f(z) of the form f(z) = z +a2z2 + ··· which are analytic in the open unit disc U = {z ∈ C||z| < 1}. In 1959 [5], K.
