The course will deal with mathematical foundations of matrix iterative methods, in particular Krylov subspace methods, in connection with the areas of mathematics and computer science important for understanding basic principles and the state of the art. It will formulate open questions and explain existing misunderstandings going across the fields that prevent deeper understanding and the development of the theory as well as efficient use of the methods in applications.
Aim of the course -
Last update: prof. Ing. Zdeněk Strakoš, DrSc. (22.12.2022)

Using the Krylov subspace methods case study, the course aims at helping students in developing the ability of seeing the whole context, in asking themselves questions and

in seeking deep interconnections and overcoming narrowly specialized sights that restrict so much needed communication across the fields. Therefore the course will combine formulation and addressing questions in infinite dimensional Hilbert spaces using elements of linear functional analysis and spectral theory of operatots with traditional matrix approach. The course will also require self-study reading of selected publications followed by discussion.

The course will cover primarily projection methods and, in particular, Krylov subspace methods in relation to the problem of moments and related issues. The emphasis will be on interconnections between the relevant topics from various disciplines, including the elements of numerical solution of partial differential equations, approximation theory and functional analysis.

Tentative content:

1. Projection processes.

2. Krylov subspaces.

3. Basic methods.

4. Stieltjes moment problem.

5. Orthogonal polynomials, continued fractions, Gauss-Christoffel quadrature and model reduction .

6. Matrix representation and the method of conjugate gradients.

7. Vorobyev method of moments and non-symmetric generalizations.

8. Non-normality and spectral information.
