Course detail

Fourier Analysis

FSI-SFA-A Acad. year: 2021/2022 Summer semester

The course is devoted to basic properties of Fourier Analysis and illustrations of its techniques on examples. In particular, problems on reprezentations of functions, Fourier and Laplace transformations, their properties and applications are studied.

Language of instruction

English

Number of ECTS credits

4

Learning outcomes of the course unit

Knowledge of basic topics of Fourier Analysis, manely, Fourier series, Fourier and Laplace transformations, and ability to apply this knowledge in practice.

Prerequisites

Calculus, basic konwledge of linear functional analysis, measure theory.

Planned learning activities and teaching methods

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

Participation in the seminars is mandatory.
Course-unit credit is awarded on condition of having attended the seminars actively and passed the control test.
Examination has a practical and a theoretical part. In the practical part student has to illustrate the given tasks on particular examples.
Theoretical part includes questions related to the subject-matter presented at the lectures.

Aims

The aim of the course is to familiarise students with basic topics and techniques of the Fourier analysis used in other mathematical subjects

Specification of controlled education, way of implementation and compensation for absences

Absence has to be made up by self-study using recommended literature.
