| 授業の目的 【日本語】 | | Title: Ergodic theory and fractal geometry for conformal dynamical systems
Dynamical systems provide mathematical models to analyse the time dependence of systems in basically all sciences and our daily life. In this seminar, we study chaotic conformal dynamical systems from the view point of ergodic theory with applications to fractal geometry.
The aim is to enable the students to perform research in the area of ergodic theory and dynamcal systems with applications to fractal geometry. We provide the necessary guidance so that the student can enter this research area and develop its own ideas. A further aim is to enable the students to improve their ability to communicate in English. |
| | | 授業の目的 【英語】 | | | | | 到達目標 【日本語】 | | | To develop a deeper understanding and knowledge of the mathematics related to ergodic theory and dynamical systems. Further, the capability to contribute to the research on topics related to this seminar. A thesis should be written at the end of the seminar course. |
| | | 到達目標 【英語】 | | | | | 授業の内容や構成 | | A dynamical systems is given by a self-map on a (state) space. Chaos refers to the sensitive dependence of orbits on the initial value. For chaotic systems it is difficult to predict and to analyse the individual behavior of orbit points. The same applies to large particle systems. Ergodic theory aims to analyse the average long-term behavior of such systems from the viewpoint of probability measures. We focus in particular on the so-called thermodynamic formalism originating from statistical physics, which allows us to determine meaningful measures for a given dynamical system.
Chaotic behavior of dynamical systems is often related to highly irregular sets (such as Julia sets of complex polynomials) which are called fractal sets. In this seminar, we study the interplay of ergodic theory, dynamical systems and fractal geometry for conformal dynamical systems.
The seminar is used to discuss research problems and ideas how to deal with them. Moreover, the seminar helps to monitor progress and timeline of the research project. For the main part of this course, the student is expected to take the responsibility to organise his research activities, and to monitor and manage his time. |
