Learning activities and methodology

The lectures aim to provide the students with the abilities mentioned before. They will be structured as follows:
i) The teacher will present the main topics and techniques of the course using the necessary technical support. The necessary bibliography will be presented in order to complement the students background. During these lectures the students will
ii) Solutions of practical exercises and problems by the teacher and students (individually or in groups).
In addition, there will personal or group tutorships where the students may ask questions to complete their understanding of the lectures and of the problems proposed.
