Educational aims & objectives

The purpose of the module is to introduce the notions of Fourier series and Fourier transform and to study their basic properties. The main part of the module will be devoted to the one dimensional case in order to simplify the definitions and proofs. Many multidimensional results are obtained in the same manner, and those results may also be stated. The Fourier technique is important in various fields, in particular, in the theory of (partial) differential equations. It will be explained how one can solve some integral and differential equations and study the properties of their solutions using this technique.

Teaching pattern

Three hours of lectures and one hour of tutorial per week throughout the term
