  • 1 ECTS point corresponds to 25-30 hours of student work needed to achieve the assumed learning outcomes;
  • weekly student workload necessary to achieve the assumed learning outcomes allows to obtain 1.5 ECTS;
  • work required to pass the course, which has been assigned 3 ECTS, constitutes 10% of the semester student load.

Full description:

The lectures have an interdisciplinary character and is directed to the graduate students who are interested in hot topics of advanced statistical physics and chaotic dynamics which are connected with non-Gaussian stochastic processes and some of their applications. During the lectures is presented their experimental basis; mainly non-Debye relaxation of photocurrents in amorphous films. The non-Gaussian (mainly Lévy processes) are considered by using the continuous-time random walk formalism and Weierstrass-Mandelbrot reprersentation of the basic, so called waiting-time distribution. Concluding: the role of the non-Gassian processes in physics and in financial markets is emphasized.

Learning outcomes:

After completion of the course the student obtained the following results in the field of education.

KNOWLEDGE

1) He knows the most important issues of the non-Gaussian stochastic chains and processes in particular knowledge on the Levy flight and walk, fat-tailed distributions and their applications in widely-understood physics.

2) He knows the basic problems of theory of extreme events.

3) He knows the canonical version of the continuous-time random walk theory.

SKILLS

1) He can distinguish Gaussian stochastic processes from the non-Gaussian ones by understanding the conditions in which both classes of processes are created and the properties that characterize them.

2) Knows how to solve problems associated with various non-Gaussian chains and stochastic processes. In particular, he knows how to read the characteristics of the processes from the empirical data.

3) Knows how to bring out the Gaussian process from the empirical time series.

ATTITUDES
