Course objectives
Complex analysis is a classic part of mathematical analysis. It has various smart and often unexpected applications in many fields of mathematics. It is an effective tool even outside the mathematics, especially in physics and engineering. The basic goal of the course is to familiarize the students with the fundamentals of the theory of functions of one complex variable, especially with integration in C and Cauchy's theory, properties of holomorphic functions, calculus of residues and its applications.
Learning outcomes
After passing the course, the student will be able:
to define and interpret the basic notions used in the basic parts of Complex analysis and to explain their mutual context;
to formulate relevant mathematical theorems and statements and to explain methods of their proofs;
to use effective techniques utilized in basic fields of Complex analysis;
to compare differences between the theory of functions of a complex variable and the theory of functions of real variables;
to apply acquired pieces of knowledge for the solution of specific problems including problems of applicative character.
Syllabus
  • 1. Introduction to the discipline: complex numbers, straight line, circle, generalized circle, afinity in C and its special cases, topological concepts, stereographic projection, Gauss and extended Gauss plane, sequences and series of complex numbers.
