Academic year 2023/2024
Supervisor: prof. RNDr. Miloslav Druckmüller, CSc.  
Supervising institute: ÚM all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:

The aim of the course is to familiarise students with elements of complex analysis and with Fourier transform including applications.  

Learning outcomes and competences:

The course provides students with basic knowledge and skills necessary for using the ecomplex numbers, integrals and residue, usage of  Fourier transforms.

Prerequisites:
Real variable analysis at the basic course level
Course contents:

The aim of the course is to make students familiar with the fundamentals of complex variable functions and Fourier transform.

Teaching methods and criteria:
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.
Assesment methods and criteria linked to learning outcomes:

Course-unit credit based on a written test.
Exam has a written and an oral part.

Controlled participation in lessons:

Missed lessons can be compensated via a written test.
