## Exercises

- Sheets with exercises will be handed out during the course.

## 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
apperntly different fields.

The course is intended to be taken together with the course
Partial differential Equations with Distribution Theory, FMA 250,
(using the same course literature), but can without problems be read
as a standalone course.
