## FMAN15, 7,5 credits, A (Second Cycle)

Valid for: 2015/16
Decided by: Education Board B
Date of Decision: 2015-04-16

## General Information

Elective for: D4, F4, F4-bs, F4-bm, Pi4-bs, Pi4-ssr, Pi4-biek
Language of instruction: The course will be given in English

## Aim

To give knowledge of and familiarity with concepts and methods from the theory of dynamical systems which are important in applications within almost all subjects in science and technology. In addition, the course should develop the student's general ability to assimilate and communicate mathematical theory, to express problems from science and technology in mathematical terms and to solve problems using the theory of dynamical systems.

## Learning outcomes

Knowledge and understanding
For a passing grade the student must

• independently be able to explain different methods to describe, qualitatively or quantitatively, the solution sets of ordinary differential and difference equations.
• be able to explain basic bifurcation theory and its relevance in technological contexts.
• be able to explain the mathematical meaning of the concept chaotic behaviour and its relevance in technological contexts.

Competences and skills
For a passing grade the student must

• be able to choose and use methods appropriate to describe, qualitatively and quantitatively, the solution sets of ordinary differential and difference equations.
• be able to use bifurcation theory to qualitatively describe  how dynamical systems taken from applications in science and technology depend on a parameter.
• be able independently to identify and describe chaotic behaviour in examples taken from the applications.
• be able to write Matlab and Maple programs to solve mathematical problems within the framework of the course.
• in writing and orally, with clear logic and proper terminology, be able to explain the solution to a mathematical problem within the course.
• with access to the resources of a library, be able to independently assimilate and summarize the contents of a text in technology in which methods and results from the theory of dynamical systems are used.

## Contents

Dynamical systems in discrete and continuous time. The fixed point theorem and Picard's theorem on the existence and uniqueness of solutions to ordinary differential equations. Phase space analysis and Poincaré's geometrical methods. Local stability theory (Liapunov's method and Hartman-Grobman's theorem). The central manifold theorem. Basic local bifurcation theory. Global bifurcations and transition to chaos. Chaotic and strange attractors (dynamics, combinatorial description).
