Learning outcomes
On completion of the course, the student should be able to:
- report on fundamental properties of Hilbert space;
- define a compact operator and report on fundamental properties of the latter;
- report on fundamental properties of Banach space;
- apply Hahn-Banach theorem, open mapping theorem, closed graph theorem and uniform boundedness principle (Banach-Steinhaus theorem);
- solve problems involving weak topology;
- solve problems in fixed points;
- solve variational problems;
- formulate the sepctral theorem;
- apply fundamental properties of unbounded operators.

Assessment
A small project with oral presentation.
If there are special reasons for doing so, an examiner may make an exception from the method of assessment indicated and allow a student to be assessed by another method. An example of special reasons might be a certificate regarding special pedagogical support from the disability coordinator of the university.
