This distinction manifests itself in the famous ., a system of two partial differential equations which couple the real and the imaginary parts of a complex differentiable function.

Complex Functions,The functions we shall be exploring in this book are complex-valued functions of a single complex variable. When we speak of ., we do not necessarily mean that these functions are analytic, although emphasis will be placed on this special and extremely important class.

滔滔不绝地说

Conformal Mappings,The focus of this chapter is on geometric aspects: complex functions will be considered as mappings between subsets of two complex planes which transplant objects from one plane to the other.

Genteel

Riemann Surfaces,In Section 3.6 we have seen that the process of analytic continuation may result in “multiple-valued” functions. Notwithstanding their name, these objects are not ordinary functions and must be handled with care.

ng complex functions in teaching, mathematical research and .This book provides a systematic introduction to functions of one complex variable. Its novel feature is the consistent use of special color representations – so-called phase portraits – which visualize functions as images on their domains.

Getting Acquainted,ions can be depicted easily in a plane, the graph of a complex function in one variable is a surface in four-dimensional space. Since our imagination is trained in three dimensions, most of us have difficulties in ‘seeing’ such an object.
