3. apply the Ljapunov method for estimating of sensitivity of processes
4. explain the importance of fractal sets and geometry in describing of chaotic iterators
5. manipulate with calculus of the theory of stability: stability of fixed points
6. manipulate with calculus of the theory of bifurcation and chaos: periods 2 and 3
7. analyze all four states on the path to chaos for continuous iterators
8. create an own chaotic circuit from basic elements purchased in Chipoteka

#### Forms of Teaching

Lectures

Based on mathematical skills and knowledge from first year of study, some new knowledge are adopted from mathematical theory on chatocal interators; computer simulation and visualization of fractal sets; basic knowledge on the fractal geometry; calculation of chatical properties; visualization of chaos on computer.

Exams

Oral exam: students continuously can solve and present their homework; there exists a final exam for advanced students. Written exams: control test and fianl exam; seminar work.

Consultations

By appointment.

Seminars

Seminar work is free choice, but it is appropriate for higher estimates. By seminar, a student shows: creativity, independence and the level of adopted knowledge.

Acquisition of Skills

Recognition of complex systems and process in nature, measurement of chatoc properties, work with fractal sets, introducing of new aspects of thinking.
