Many dynamical systems have interesting dynamics at several time scales (think weather vs climate). The resulting phenomena can be difficult to capture using classical ODE-theory and thus new tools are required. The goal of this talk is to introduce fast/slow systems, geometric singular perturbation theory and the blow-up method. The Van-der-Pol oscillator will serve as a guiding example.
