Detail of lecture’s hours: 
Lesson (80 hours)

Knowledge of mathematical analysis and general topology as usually studied in a first level degree program in mathematics.

Final Examination: 

The exam is divided into two parts:
- a written part, consisting in solving two exercises chosen from a list of problems assigned at the end of the course, where the student shows to have acquired an operating knowledge of the subject and to be able to apply the techniques described in class,
- an oral examination consisting in the discussion of the exercises and to the proof of one or two theorems seen in class.

Voto Finale

The aim of the course is to provide the fundamental notions of functional analysis, illustrating the methods and the most significant techniques of proof.

After the course students
- will know the statement and proof of the main theorems seen in class;
- will have acquired an operating knowledge of the methods and techniques of Functional Analysis;
- will be able to apply the abstract results studied in class to particular cases;
- will be able to apply the techniques of proof learned in class to prove theorems similar to thosee prove in class and to solve problems of theoretical nature.
