In the present paper, we determine the mapping properties of analytic function h (z) in the
unit disc U={z:| z|< 1}, defined by h (z)=(1-)(z)+ z'(z) where> 0 and (z)= zF (abcz): Our results …

A function f (z)= z−∑ n= 2∞ anzn, an⩾ 0, is said to be in the family F ({bn}) if there exists a
sequence {bn} of positive real numbers such that∑ n= 2∞ bnan⩽ 1. All functions in F ({bn}) …

The authors present a systematic investigation of various interesting properties of a certain
subclass of starlike functions with negative coefficients. In particular, they give numerous …
