The Grunsky inequalities imply many inequalities for univalent functions. They were also used by Schiffer and Charzynski in to give a completely elementary proof of the Bieberbach conjecture for the fourth coefficient; a far more complicated proof had previously been found by Schiffer and Garabedian in In Pedersen and Ozawa independently used the Grunsky inequalities to prove.

In complex analysis, de Branges's theorem, or the Bieberbach conjecture, is a theorem that gives a necessary condition on a holomorphic function in order for it to map the open unit disk of the complex plane injectively to the complex plane.

It was posed by Ludwig Bieberbach () and finally proven by Louis de Branges (). The statement concerns the Taylor coefficients a n of a univalent.

Journal of Inequalities in Pure and Applied by: 2. Abstract. A function analytic in the open unit disk is said to be bi-univalent in if both the function and its inverse map are univalent there. The bi-univalency condition imposed on the functions analytic in makes the behavior of their coefficients unpredictable.

Not much is known about the behavior of the higher order coefficients of classes of bi-univalent by:   A characterization of meromorphically q-starlike functions associated with the Janowski functions has been obtained when the coefficients in their Laurent series expansion about the origin are all positive.

This leads to a study of coefficient estimates, distortion theorems, partial sums, and the radius of starlikeness estimates for this by: 6. Inequalities Vol Number 2 (), – doi/jmi SOME COEFFICIENT INEQUALITIES RELATED TO THE HANKEL DETERMINANT FOR STRONGLY STARLIKE FUNCTIONS OF ORDER ALPHA N.

(source: Nielsen Book Data) Summary Complex Analysis: Conformal Inequalities and the Bieberbach Conjecture discusses the mathematical analysis created around the Bieberbach conjecture, which is responsible for the development of many beautiful aspects of complex analysis, especially in the geometric-function theory of univalent functions.

Coefficient estimates for negative powers of the derivative of univalent functions Thus, if Cn,p for infinitely many n. This also holds if -l max{21p I - 1, 0}. It is proved, for example, that the estimate, where for and for, holds for such functions f, and that it is best possible for each fixed within the class and for each fixed within the class.

It is also shown that the inequality, which holds for all bounded univalent functions, cannot be improved for bounded. You can write a book review and share your experiences.
