On Zalcman's and Bieberbach conjectures
Abstract
The well-known Zalcman conjecture, which implies the Bieberbach conjecture, states that the coefficients of univalent functions on the unit disk satisfy for all , with equality only for the Koebe function and its rotations. The conjecture was proved by the author for (using geometric arguments related to the Ahlfors-Schwarz lemma) and remains open for . The main theorem of this paper states that these conjectures are equivalent and provides their simultaneous proof for all combining the indicated geometric arguments with a new author's approach to extremal problems for holomorphic functions based on lifting the rotationally homogeneous coefficient functionals to the Bers fiber space over universal Teichmuller space.
