Course completion requirements

The credit for exercises is awarded provided the student enrolls in the course. The credit from exercises is required to participate at the exam. The exam consists of a written computational part and oral theoretical part. Students failing in the test are not allowed to continue with the oral part. Students failing in the oral part must go through both parts (written and oral) in their next attempt.

Syllabus -

1. Linear spaces

algebraic version of Hahn-Banach theorem

2. Hilbert spaces (a survey of results from the course in mathematical analysis :

orthogonal projection; orthogonalization; abstract Fourier series; representation of Hilbert space

3. Normed linear spaces; Banach spaces

bounded linear operators and functionals; representation of bounded linear functionals in a Hilbert space; Hahn-Banach theorem; dual space; reflexivity; Banach-Steinhaus theorem; open map theorem and closed graph theorem; inverse operator; spectrum of the operator; compact operator; examples of Banach spaces and their duals (integrable functions, continuous functions)
