Getting basic theoretical knowledge in modern harmonic analysis. Attaining practical skills which will allow the PhD students to use all these approaches effectively in computer-aided modeling and research of real systems.

Linear algebra, differential and integration calculus, linear functional analysis.

Not applicable.

The course is taught through lectures and/or seminars targeted at selected topics of the discipline.

Seminar presentations and/or oral examination.

Not applicable.

Not applicable.

The PhD students will be made familiar with the latest achievements of the modern harmonic analysis and their applicability for the solution of practical problems of functional modeling in abstract spaces, in particular in l^2(J) (the space of discrete signals incl. images), L^2(R) (the space of analog signals) and L^2(Omega;A;P) (stochastic linear time series models).
Attention will be paid also to the problems of finding numerically stable sparse solutions in models with a large number of parameters.

Absence has to be made up by self-study and possibly via assigned homework.
