SSD: FIS/02

CFU: 3 CFU + assignment: 2 CFU

Period: April-May 2024

Lessons / Hours: 12 hours, divided in six 2-hours lectures (weekly) 

Program:

Asymptotic symmetry groups:

  • The BMS group
  • The Weyl BMS group

Verification: Written exam about applications of the formalism discussed during the lectures to a specific case

Prerequisites: Basics of differential calculus and general relativity (students lacking this background are encouraged to make contact in advance with the teacher, as a crash course on necessary prerequisites can be provided on demand)
