Basic notions and results are addressed concerning successively topological spaces, metric spaces, topological vector spaces, normed and Banach spaces, Hilbert spaces.


The complete introductory course in mathematical analysis and linear algebra on level A or B given at the Faculty of Nuclear Sciences and Physical Engineering

Syllabus of lectures:

1. Topological spaces

2. Metric spaces, compactness criteria, completion of a metric space

3. Topological vector spaces

4. Minkowski functional, the Hahn-Banach theorem

6. Metric vector spaces, Fréchet spaces

6. Normed vector spaces, bounded linear mappings, the operator norm

7. Banach spaces, extension of a bounded operator

8. Banach spaces of integrable functions

9. Hilbert spaces, orthogonal projection, orthogonal basis

10. The Riesz representation theorem, adjoint operator

Syllabus of tutorials:

Exercise is closely linked to the lecture, which is illustrated by appropriate examples. Accent is placed on the correctness of the calculation.

1. Basics of topology, repetition.

2. Basics of metric spaces and of banach spaces.

3. Banach spaces and linear bounded mappings

4. Resolvent formula, Fourier transform

5. Scalar product, isomorphism of Hilbert spaces orthogonality

7. Norms, continuity, linear extension, projectors, types of convergence

8. Spectral properties of normal and compact operators, ideals of compact operators

Study Objective:

Knowledge: basics of Banach and Hilbert spaces and linear operators in these spaces, and as a background sufficiently profound knowledge of topological and metric spaces

Skills: applications of the apparatus of Banach and Hilbert spaces
