Requirements: 

The content of Mathematical Analysis 1-3, Linear Algebra and Geometry, Geometry 1

Final Examination: 
Orale

- Homework exercises which verify the acquisition of an operational knowledge of the subject and the ability to apply the techniques illustrated in class to produce independently proofs of statements similar to those seen in in the lectures and to express themselves in rigorous mathematical language.

- Final oral exam devoted to the discussion of the homework exercises, and to the proof of one or two theorems seen in class. This part will assess the acquisition of an in-depth knowledge of the topics presented in class and the students' ability to express themselves in a rigorous mathematical language and to recognize the validity of, even subtle, mathematical reasoning.

Assessment: 
Voto Finale

The aim of the course aims is to deepen the study of modern analysis begun in the previous courses.
Students will acquire a working knowledge of the methods of advanced analysis. They will know statements and proofs of the main theorems, and will be able to solve exercises, even of theoretical nature, on the topics treated in the course. They will have learned a number of techniques of proof which they will be able to use to recognize the validity of sophisticated mathematical reasoning and to prove results related to those described in class. Finally students will be able to express themselves in a rigorous mathematical language.
