    This book deals with the theory of convex and starlike biholomorphic mappings in several complex variables. The underlying theme is the extension to several complex variables of geometric aspects of the classical theory of univalent functions. This is the first book which systematically studies this topic. It gathers together, and presents in a unified manner, the current state of affairs for convex and starlike biholomorphic mappings in several complex variables. The majority of the results presented are due to the author, his co-workers and his students. Audience: This volume will be of interest to research mathematicians whose work involves several complex variables and one complex variable.

It is proved that the class of ε quasi-convex mappings is a proper subset of the class of starlike mappings and contains the class of ε starlike mappings properly for some ε∈[−1,0)∪(0,1].

Let be the class of all convex functions in normalized by the conditions, ; let, be the subclasses of consisting of functions that map onto convex domains of the -plane with a -fold symmetry of rotation about the point.

CONVEX MAPPINGS IN SEVERAL COMPLEX VARIABLES HIDETAKA HAMADA AND GABRIELA KOHR Kyushy Kyoritsu Univ., Japan and Babe§-Bolyai Univ., Romania ABSTRACT.

Let B be the unit ball of en with respect to an arbitrary norm. We will give a sufficient condition for a local diffeomorphism of C1 class on B to be univalent and to have a convex image. Finally. Let B n be the Euclidean unit ball in C n.

In this paper, we study several properties of strongly starlike mappings of order α (0. It introduces the infinite-dimensional theory and provides numerous exercises in each chapter for further study.

The authors present such topics as linear invariance in the unit disc, Bloch functions and the Bloch constant, and growth, covering and distortion results for starlike and. G-LOEWNER CHAINS AND PARABOLIC STARLIKE MAPPINGS IN SEVERAL COMPLEX VARIABLES1 S.

In the Sections 3 and 4 we introduce and study the classes of starlike, con-vex and alpha-convex functions of hyperbolic complex and of dual complex variable, respectively. The methods were suggested by the classical ones in [].

Preliminaries First let us recall some known facts about the complex-type numbers (see e.g. [6], []). A twice continuously differentiable function of several variables is convex on a convex set if and only if its Hessian matrix of second partial derivatives is positive semidefinite on the interior of the convex set.

Any local minimum of a convex function is also a global minimum. A strictly convex function will have at most one global minimum. CONVEX AND STARLIKE UNIVALENT FUNCTIONS BY S. BERNARDI 1. Introduction.

In this paper, we investigate rigidity and its applications to extreme points of biholomorphic convex mappings on Reinhardt domains. By introducing a version of the scaling method, we precisely construct many unbounded convex mappings with only one infinite discontinuity on the boundary of this domain.

We also give a rigidity of these unbounded convex mappings via the Kobayashi metric and the Author: Taishun Liu, Xiaomin Tang, Jianfei Wang. A convex function. Image: Eli Osherovich. Convex or concave. It's a question we usually answer just by looking at something.

It's convex if it bulges outwards and concave if it bulges when it comes to mathematical functions, things aren't that simple. A team of computer scientists from the Massachusetts Institute of Technology have recently shown that deciding.

The main purpose of this paper is to introduce two classes P β (λ,b) and R β (λ,b) (b, a complex number with Re(b)>0) of functions which are analytic in the unit cient estimates for functions in these classes and radii of close-to convexity, starlikeness and convexity are by:   The main theme is the extension of geometric function theory methods and theorems to several complex variables.

The papers present various results on the growth of mappings in various classes as well as observations about the boundary behavior of mappings, via developing and using some semi group methods.

The usual convex set is the real linear convex set, if we change the real linear map into complex linear map, we can get the complex convex set. A system way to do this is in the several complex analysis, at wiki here: Holomorphically convex hull, changing the holomorphic functions into complex linear functions.
