Learning objectives
The aim of the course consists in introducing students to fundamental questions of the modern Real Analysis paying particular attention to how these concepts can be used to solve both integral an differential equations.
Expected learning outcomes
Students will acquire familiarity with the basic properties of the real analysis, with particular focus on the theory of Lebesgue and Hilbert' s spaces. They will be able to produce autonomously proofs of simple statements (homeworks), and to explain rigorously the knowledges and connected problems learnt in the lectures. Moreover they will have the opportunity of working in groups.
