### Introduction to Mathematical Chaos Theory for Engineers

#### Course Description

#### General Competencies

General knowledge on the history of the Mathematical theory of chaos. Mathematical calculation of basic elements of Mathematical theory of chaos: fixed points, stability, periodic points, bifurcation, sensitive dependence on intial conditions. Basic knowledge on fractal geometry: mathematical generation of fractals, self similarities, fractal dimensions. Basic criteria for chaotic behaviour of continuous iterators.

#### Learning Outcomes

- describe fundamental properties which characterize chaotic iterators
- distinguish linear, nonlinear, nonchaotic and chaotic iteration processes
- apply the Ljapunov method for estimating of sensitivity of processes
- explain the importance of fractal sets and geometry in describing of chaotic iterators
- manipulate with calculus of the theory of stability: stability of fixed points
- manipulate with calculus of the theory of bifurcation and chaos: periods 2 and 3
- analyze all four states on the path to chaos for continuous iterators
- 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.
