Dynamical Systems and Mathematical Modelling (FSI-SA0)

Academic year 2023/2024
Supervisor: prof. RNDr. Jan Čermák, CSc.  
Supervising institute: ÚM all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:

The aim of the course is to explain basics of the theory of stability, bifurcations and chaos for ordinary differential and difference equations, including time delay equations.  The task of the course is to demonstrate the obtained knowledge in mathematical modelling via dynamic equations, including analysis of  their solutions.
Learning outcomes and competences:

Students will acquire knowledge of basic methods  for analysis of stability, bifurcations and chaos for ordinary differential  and difference equations. They also will master basic procedures  of mathematical modelling by means of studied types of equations , including methods of qualitative analysis of their solutions. 
Prerequisites:

Differential and integral calculus of functions in a single and more variables, theory of ordinary differential equations, linear algebra.
Course contents:

The course provides basics of theory of stability, bifurcations and chaos for continuous and discrete dynamic systems.  Applications of the obtained  knowledge in the study of  various problems in technical and scientific branches are stated as well. The study of these problems consists in forming of a differential or difference equation as a corresponding mathematical model, and in analysis of its solution. 
Teaching methods and criteria:

The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on mathematical modelling via differential equations, and on practical topics presented in lectures.

 

 
Assesment methods and criteria linked to learning outcomes:

Course-unit credit is awarded on the following conditions: Active participation in seminars. Fulfilment of all conditions of the running control of knowledge. 

Examination: The examination tests the knowledge of definitions and theorems (especially the ability of their application to the given problems) and practical skills in solving of examples. The exam is written and oral, the written part (60 minutes) consists of the following topics: Stability of linear and nonlinear ODEs, bifurcation, chaos, ODEs with a time delay, difference equations. 

The final grade reflects the result of the written and oral part of the exam (maximum 100 points).
Grading scheme is as follows: excellent (90-100 points), very good (80-89 points), good (70-79 points), satisfactory (60-69 points), sufficient (50-59 points), failed (0-49 points).
Controlled participation in lessons:

Attendance at lectures is recommended, attendance at seminars is obligatory and checked. Lessons are planned according to the week schedules. Absence from seminars may be compensated for by the agreement with the teacher.
