Learning outcomes
Knowledge
Basic knowledge on matrix algebra and linear dynamical systems, on the concepts of stability, equilibrium, first integral, on finite difference equations.
Specific knowledge on qualitative theory of dynamical systems, especially in the plane, on conservative systems with Newton. Lagrange and Hamilton formalism, on discretization of ordinary differential euqations, on non-integrable and chaotic dynamical systems.
Significant examples of applications to problems in mechanics, in economics, and in model problems.
