Synopsis:

Advanced parts of functional analysis needed for theory of representations of Lie groups and quantum theory. Compact

operators, their ideals, unbounded selfadjoint operators, theory of selfadjoint extension of symmetric operators, Stone’s

theorem, quadratic forms and Bochner integral. The basics of Banach algebras and C*-algebras.

Requirements:

Basic calculus and linear algebra courses (01MANA, 01MAA2-4, 01LALA, 01LAA2), the first two parts of Functional analysis course (01FAN1, 01FA2).

Syllabus of lectures:

1. Basics of theory of Banach and Hilbert spaces, bounded linear operators, closed linear operators, Hilbert-Schmidt

2. Tensor product of Hilbert spaces.

3. Compact operators in Banach and Hilbert spaces.

4. Ideals of compact operators.

6. Spectral theorem for unbounded selfadjoint operators.

7. Oneparametric groups of unitary operators, Stone’s theorem.

8. Quadratic forms, representation theorem, Friedrich’s extension.

9. Bochner integral.

10. Banach algebras, C*-algebras.

Syllabus of tutorials:

1. Summarization of properties of bounded operators on Hilbert spaces.

2. Compact operators.

3. Symmetric, selfadjoint, closed operators. Essential spectrum.

Study Objective:

The goal of study is to finish the basic functional analysis course oriented mainly on modern quantum theory and solving of problems which arise in physical and technical applications.
