PhD course: "Nonlinear network systems"
Teachers: Giacomo Como, Fabio Fagnani, Mark Jeeninga
The aim of this course is to introduce the PhD students to the theory of nonlinear dynamical systems, with particular focus on techniques for the analysis of (large-scale) network systems. A number of timely applications in the natural, engineering, and socio-economic sciences will also be presented and studied.
The course will be structured in 15 lectures (30 hours total) to be held weekly at DISMA. The first lecture is scheduled on Wednesday, November 10 10:30-12:30 in Aula Buzano, Politecnico di Torino.
