Numerical Integration of dynamical systems


In this course we will introduce and study numerical integrators for stiff (or multiscale) differential equations and dynamical systems with special geometric structures (symplecticity, reversibility, first integrals, etc.). These numerical methods are important for many applications ranging from the numerical simulation of chemical reactions, fluid dynamics or mechanical systems, to the study of population dynamics or planetary motion.
