Learning objectives

This course means to introduce basic examples of discrete dynamical systems and the theoretical framework to study more general examples. It is an excellent review of topics studied in previous courses.


Basic differential geometry, point set topology, real and complex analysis.

Course unit content

Introduction to discrete dynamical systems. It can be useful also for students in Physics.
