#
Functional analysis and harmonic analysis

## Start

The course starts
at 10.15 on
Tuesday September 1 in MH 333.

(Due to an expected limited set of participants,
the course is planned to be held in a usual way in a classroom.)

Welcome!

## Course literature

Renardy and Rogers is
available on the net from computers connected to the LU net.

Since the course book is quite theoretical complete Lecture notes covering the material will be handed out during the course together with exercises.

## Secondary literature

In Mathematical structures there are
background material to parts of the course.

## Exercises

Sheets with exercises will be handed out during the course.

The exercises are discussed during the exercise sessions every second Friday.

## Repetition questions

To recieve a pass in the oral exam one should do well on the following
repetition questions.

## Time and place

Tuesday 10-12 and Friday 13-15 in MH 333 (see timeedit).

## Supplementary reading

The following are three books on functional analysis
which are free on the net.

## Aim

Functional analysis and harmonic analysis are fundamental tools
in many important areas of abstract and applied mathematics
as well as mathematical statistics and numerical analysis.
The aim of the course is to convey knowledge about basic concepts
and methods, and to give the ability, both to follow discussions
where these are used and to independenty solve mathematical
problens which arise in the applications. An important goal
of the course is also to develop a power of abstraction which
makes it easier to see analogies between problems from
apperently different fields.
