Learning objectives

Knowledge and understanding:
At the end of this course the student should know the essential definitions and results of the analysis in more variables, and he should be able to grasp how these enter in the solution to 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 will be used in a more applied context.

Making judgements:
The student should be able to evaluate coherence and correctness of the results obtained by himself or offered him.

Communication skills:
The student should be able to communicate in a clear and precise way, also in a context broader than mere calculus.

Prerequisites

It is compulsory to pass the exams of Mathematical Analysis 1 and Geometry before facing Mathematical Analysis 2.

Bibliography

Any book of Elements of Mathematical Analysis 2.
Lecture notes of the teacher will be available at the end of the course.

Teaching methods

Teaching will consist of lectures conducted by the teacher on the blackboard and in exercises designed to illustrate and apply the theory performed earlier.

Assessment methods and criteria

No test is expected during the course.
There will be a final written exam with both closed and free answers, lasting three hours. After passing the written exam an oral colloquium with a discussion of the exercises and of the related theoretical results is mandatory.
