SF1691 Complex Analysis 7.5 credits
Complex analysis deals with functions of a complex variable, especially derivatives and integrals of such functions. Holomorphic funktions, i.e. functions that are differentiable in a complex sense, have a number of interesting properties and applications. It turns out that the so-called imaginary number i is very useful in investigating phenomena in our real reality. This course will be taught in Swedish.

Content and learning outcomes
Course contents
Intended learning outcomes
After the course the student should be able to
- explain the meaning of basic concepts, theorems and methods within the parts of complex analysis described by the course content
- use concepts. theorems and methods to solve and present solutions to problems within the parts of complex analysis described by the course content,
in order to solve applied problems and to communicate with the help of mathematical language, even in other contexts.
For higher grades, the student should in addition be able to
- explain how different theorems and concepts are connected and deduce relationships from the given theorems.
