The lectures are delivered in Italian.
This course deals with important topics in Functional Analysis and Operator Theory, which complete and develop the ones already covered in the previous course of Functional Analysis 1.
To provide some fundamental contents in Functional Analysis and Operator Theory that are considered important for the students who want to follow a PhD, or anyway aim to get a well grounded knowledge in the basic branches of Mathematics.
To provide some fundamental contents in Functional Analysis and Operator Theory.
Expected learning outcomes:
The students will become acquainted with the concepts and proofs carried out in class and how they are used in practice to solve exercises; moreover they will know how to produce easy variants of demonstrations seen and construct examples on topics covered in this course.
Mathematical Analysis I, 2, 3 and 4, Linear Algebra and Analitic Geometry, Geometry 1, Functional Analysis 1.
Lectures (52 hours). Both theory and exercises are presented by the teacher in the usual way. Moreover some tutorial exercitations will be carried out during the semester.
Weak topologies; compactness in spaces of continuous functions: the Ascoli-Arzelà theorem; elements of operator theory: the spectrum, the adjoint operator, compact operators, the spectral theorem for compact selfadjoint operators, the spectral radius.

Written and oral tests. Oral test, which students can access whatever the outcome of written test, has to be taken in the same exam session of written test.
Students with disabilities or specific learning disorders (SLD) are reminded that, in order to be enabled to request specfic arrangements during exams, they must before insert certification on the website of the University, on the page servizionline.unige.it section “Studenti”. All relevant information is available on the University website: https://unige.it/disabilita-dsa
The written examination consists in an exercise about the topics covered in this course. In this test the ability to apply theoretical results in concrete situations is evaluated.
The test lasts an hour and a half and it is possible to consult the notes and textbooks.
In the oral exam a discussion of the written examination is done; moreover some questions are asked on the course content and/or about the solution of some exercises about the topics covered in this course. In such way they are assessed the understanding, the knowledge of the concepts, and the skills in using them, acquired by the students.
Attendance is recommended.
Students are suggested to enroll in AulaWeb, in order to be able to get further information by the teacher about the course.
