Functions Starlike With Respect To A Boundary Point

Let u = i z : izi < l} be the unit disk and s be the class of analytic univalent functions f normalized such that i(o) = f'(d) -l = o. Let s* denote the subclass of functions f in s which satisfy the condition rei zf'(z) / fez) } > o, z e u. Functions f e s* map u univalently onto...
