1. Sequences and series of functions
Pointwise convergence, uniform convergence.
Total convergence of series of functions.
Power series, Fourier series.

2. Functions of n real variables
Vector spaces. Scalar product (Cauchy-Schwarz inequality), norm, distance,
standard topology, compactness in Rn.

Continuous functions from Rn to Rm. Continuity and uniform continuity. Weierstrass theorem.

Hessian matrix is ​​positive (negative) are minimum (maximum) points; the points
critics in which the Hessian matrix has a positive and a negative eigenvalue are saddles.

composition.

3. Normed spaces and Banach spaces
Examples. Converging and Cauchy sequences. Equivalent rules. Equivalence of the norms in Rn. The space of the
continuous functions with the sup norm a Banach space.

Type of delivery of the course

4 hours of frontal teaching 2 of exercises and 2 of tutoring a week

Attendance

course attendance is strongly recommended

Type of evaluation

The written exam focuses on the topics covered in class and tends to verify the ability to solve exercises. It consists of 4 exercises on the topics discussed during the class. The oral exam verifies the ability to present and prove the theorems studied in class and apply them in specific cases.

Type of delivery of the course

Lectures and exercises in class. All the material of the program will be explained in class. The lessons / exercises will include a continuous dialogue with the students: the feedback from the students during the course is a fundamental tool for the success of the course itself. In the event of an extension of the health emergency from COVID-19, all the provisions (of the State and of the Roma Tre University) governing the methods of carrying out educational activities will be implemented. In particular, distance learning may be necessary.

Attendance

Attendance is optional and the understanding of the text adopted is sufficient for the full use of the course. Of course, attendance is desirable and STRONGLY recommended, as the interaction between teacher and students is a fundamental and unrepeatable teaching tool.

Type of evaluation

The evaluation is based on a written test and an oral exam. There are two written tests "in progress" which, in the event of a positive outcome, replace the final written test. Examples of tests of past years will be available on the web site dedicated to the course which will be constantly updated by the teacher. In the case of an extension of the health emergency from COVID-19, all the provisions (of the State and of the Roma Tre University) that regulate the methods of student assessment will be implemented. In particular, distance assessments may be necessary and in this case the oral evaluation will be preceded by a preliminary written test which is an integral part of the oral examination.
