. Let S denote the class of analytic and univalent ( i.e. , one-to-one) functions f ( z ) = z + P ∞ n =2 a n z n in the unit disk D = { z ∈ C : | z | < 1 } . For f ∈ S , Ma proposed the generalized Zalcman conjecture that | a n a m − a n + m − 1 | ≤ ( n − 1)( m − 1) , for n ≥ 2 , m ≥ 2 , with equality only for the Koebe function k ( z ) = z/ (1 − z ) 2 and its rotations. In this paper using the properties of holomorphic motion and Krushkal’s Surgery Lemma [12], we prove the generalized Zalcman…

Generalized Zalcman Conjecture for Starlike and Typically Real Functions

Abstract Zalcman conjectured that |a2n − a2n − 1| ≤ (n − 1)2,n = 2, 3,… forf(z) = z + a2z2 + a3z3 + ··· ∈ S, the class of normalized holomorphic and univalent functionsf(z) in the unit disk D . We

Proof of the Zalcman conjecture for initial coefficients

Abstract The well-known Zalcman conjecture, which implies the Bieberbach conjecture, states that the coefficients of univalent functions on the unit disk satisfy the inequality for all n > 2, with

Holomorphic motions and polynomial hulls

A holomorphic motion of E C C over the unit disc D is a map f: DxC-?C such that f(O, w) =w, w E E, the function f(z, w) = fz(w) is holomorphic in z, and fz: EC is an injection for all z E D.

Univalent functions and holomorphic motions

We consider in this paper the coefficient problems for univalent functions slightly generalizing the Bieberbach and Zalcman conjectures and give their complete solution for the lower coefficients.
