Fundamental Newtonian mechanics; Basic Calculus
This module provides an introduction to the theory of nonlinear physics and to chaos theory, with a discussion of relevant examples in several branches of science such as physics, biology or engineering. The material is then studied in depth through extensive coursework problems.
To provide a sound grounding and the basic theorems, methods and applications of the theory of nonlinear physics. To gain computational and mathematical skill to characterise the qualitative complex systems in physics, finance, and other disciplines.
To then encourage the in-depth investigation of aspects of nonlinearity through extended coursework problems.
|Upon successful completion of the module the student will be able to appreciate the implications of nonlinearity in physics and identify its basic mechanisms. They will be able to analyse and classify the motion of complex nonlinear systems by identifying their qualitative features and by categorizing them in terms of periodic, quasi-periodic or chaotic behaviour. They will be able to recognize effects of nonlinearity in situations of everyday life.|
|On successful completion of the coursework part of the module, they will be able to apply fundamental methods of nonlinear dynamics to analyse chaotic systems and will appreciate the concept and the benefits of chaos control.|

Linear and nonlinear dynamics
• Fixed points, bifurcations in one dimension
• Fixed points, bifurcations, and limit cycles in two-dimensional systems
• Linear analysis in phase space
• Liapunov Stability and Poincaré-Bendixon theorems
• Fractals, and concepts of fractal dimensions
• Attractors, strange attractors and chaos
• Lorenz and Rössler attractors
• Measures of nonlinearity and quantification by Liapunov exponents and dimensional analysis
• Nonlinear maps and cascade route to chaos
• Unimodal maps, renormalization and Feigenbaum constants
• Examples of oscillator in two and three dimensions (van der Pol, Duffing, etc…)
• Other examples from physics, engineering and biology
Methods of Teaching / Learning
28 hours of theory lectures plus 5 hours of class exercises session (33 hours of lectures in total) and open-ended study for the coursework problems.
Exercises will be held in the form of tutorial sessions and are meant to demonstrate specific examples and applications of the material taught in class.
The coursework will focus on the study of specific nonlinear system(s) that give the student with opportunities to gain knowledge of advanced topics and to prove independent thinking and investigation skills. The assignment is handed out at mid semester and typically requires the use of computational techniques, with the results to be presented in report form at the end of the semester (usually in week 12).
There are two coursework assignments to be completed for this module, along with a final examination of 1.5h duration, in which 2 questions from 3 should be answered.
The assessment strategy is designed to provide students with the opportunity to demonstrate their insight into the physic of nonlinear and complex phenomena. The coursework assigned during the semester will give the occasion to put in practice the concepts learned in class, therefore gradually building a deeper understanding of nonlinear phenomena and mastering the techniques used for their analysis. The final exam, at the end of the semester, will assess the overall understanding of the fundamental concepts and theory of complex phenomena.
Thus, the summative assessment for this module consists of:
One coursework to be completed during the semester requiring about 5 weeks. The coursework will have to be completed at the end of the semester.
One exam at the end of the semester lasting 1.5 hours (with 2 questions to be answered out of 3).
Formative assessment and feedback
Students will have the opportunity to receive continuous feedback through discussions during class time. Assessment of the submitted coursework will be returned to the students with feedback on their performance.
