On the structure and applications of the Bondi-Metzner-Sachs group

Understand

This work is a pedagogical review dedicated to a modern description of the Bondi-Metzner-Sachs group.

• The curved space-times that will be taken into account are the ones that suitably approach, at infinity, Minkowski space-time.
• In particular we will focus on asymptotically flat space-times.
• In this work the concept of asymptotic symmetry group of those space-times will be studied.
