In this Curricular Unit an introduction to Measure Theory and Integration is made and the study of chaotic dynamical systems is developed through invariant measures, recurrence properties and entropy.
At the end of the Curricular Unit students should:
i. be able to define measure spaces and recognize some of their main features;
ii. know the fundamentals of Lebesgue integration and understand the main results about Lp spaces;
iii. know how to identify invariant measure(s) of a dynamical system and make use of it as an analysis tool;
iv. know the main ergodic theorems and their corollaries;
v. be able to define, interpret and develop the concept of entropy of a dynamical system;
vi. know and be able to work with different basic models of discrete dynamical systems;
vii. use Ergodic Theory to formulate and solve problems in different areas of Mathematics and Science.
