On the coefficient domains of univalent functions
The author considers functions \(f\) which are analytic in the interior of a certain ellipse and there satisfies \(\Re\{\sqrt{z^ 2-1}f'(z)\}>0.\) Such a function can be expanded in a series of Chebyshev polynomials and the author finds bounds on the coefficients in this expansion.
