A diagrammatic approach to perturbation theory

External Lecturer: 
Livia Corsi
Course Type: 
PhD Course
Academic Year: 
2021-2022
Period: 
January-February
Duration: 
20 h
Description: 

In this course I will present a diagrammatic approach which can be conveniently used to study perturbative series. After a general introduction, I will start by focusing on the classical KAM theorem in the "mechanical case'', and then discuss various generalizations, such as the case of more general hamiltonians, non-maximal tori, harmonic oscillators, depending on the audience preferences.
