Fundamentals of Complex Analysis

Fundamentals of Complex Analysis (MTH301)


Complex numbers, complex functions and the analysis of functions of one complex varaible are introduced. The understanding of the basic theory and the techniques of complex analysis is the ket to succesful applications. The course aims to introduce the basic fundamental concepts and show how they are woven together to provide a powerful tool for application.
