The participation and attendance of the students to the classes during the whole course will be valued. The research capacity and the preparation of the presentations will be evaluated. The evaluation is continuous so the exercises must be delivered on the date indicated throughout the course. Never out of time. The exercices will be made through the "cloud" and in person at public lecture when it be considered by the teacher prior notice. The use of the bibliography in the syllabus as of the class notes, as well as of the texts commented during the cours will be well received.
