## Learning objectives

Knowledge and understanding: At the end of this course the student should know the essential definitions and results of analysis in several variables, and he should be able to grasp how these enter in the solution of problems. Applying knowledge and understanding: The student should be able to apply the forementioned notions to solve medium level problems, and to understand how they relate to concepts seen in different courses. Making judgements: The student should be able to evaluate coherence and correctness of the proofs he gives during the written test. Communication skills: The student should be able to communicate in a clear and precise way, suitable for a scientist-to-be in an intermediate stage of his formation.

## Teaching methods

Lectures are held in the classroom, encompassing both theoretical and applied aspects. Moreover, exercises are solved by students with the guidance of the teacher, so as to verify the degree of comprehension and knowledge of the students.

## Assessment methods and criteria

The final exam consist of a written and an oral session. Students are admitted to the oral sessions only if they pass the written examination. In the written examination 2 open questions are asked. The students should exhibit calculus skills and mastery of different subjects taught in the course. Marks are given to each question, according to theoretical correctness, precision of execution, precision of exposition.
The oral examination consists of a discussion about the written examination and of questions to verify the level of comprehension of the theoretical parts of the course.
