Module aim (aims)
The main goal of this course is to offer an introduction to classical methods of appliedmathematics. We will focus on the qualitative theory of systems of ordinary differential equations (ODEs). Following a review of standard results concerning existence and uniqueness of solutions and their continuous dependence on parameters, we will study linear system, stability theory, invariant manifolds, ending with a survey of periodic and homoclinic solutions. In the optimistic variant, the specific topics to be discussed will include.
Pre-requisites in terms of knowledge, skills and social competences (where relevant)
Real analysis and basic differential equations, Linear algebra.
