Learning Objectives

The main objective of the course is to show how the contents of Mathematical Analysis I and II, learned by the student in an Euclidean setting, can be extended to the general framework of Banach spaces. Particular emphasis will be put on some meaningful applications of such extensions.

In more detail, following the Dublin descriptors, the objectives are the following:

Knowledge and understanding: the student will learn to use in the setting of Banach spaces the methods learned in the courses of Mathematical Analysis I and II.

Applying knowledge and understanding: the student will be guided in the ability to realize applications of the general results gradually established.

Making judgements: the student will be stimulated to study autonomously some results not developed during lessons.

Communication skills: the student will learn to expose in a clear, rigorous and concise manner.

Learning skills: the student will be able to face exercices and found proofs of simple results.

Course Structure

The course will be performed through frontal lessons.
