Aims

This module gives an introduction to the mathematical theory of linear and non-linear waves. Illustrative applications involve problems of acoustics, gas dynamics and examples of solitary waves.


Learning Outcomes

Students will learn essential modelling techniques in problems of  wave propagation.   They will also understand that mathematical models of the same type can be successfully used to describe different physical phenomena.   Students will also study background mathematical theory in models of acoustics, gas dynamics and water  waves.
