On starlikeness and convexity of certain analytic functions

2001
Let \(A\) denote the class of functions \[ f(z)= z+\sum^\infty_{n=z} a_n z^n \] analytic in the unit disk \(U= \{z:| z|< 1\}\) of the complex plane \(\mathbb{C}\). Let \(S(\alpha, b)\) and \(C(\alpha, b)\) denote the corresponding subclasses of \(A\) consisting of functions \(f(z)\) which satisfy in \(U\), \[ \Biggl| {zf'(z)\over f(z)}- b\Biggr|< \text{
