Martina L. Symmetries of asymptotically flat spaces and gravitational memory effect (abstract)
Speaker: Luigi Martina
Title: Symmetries of asymptotically flat spaces and gravitational memory effect
We review the conformal Carroll group and consider its relation with the Bond-Metzler-Sachs group for asymptotically flat spacetimes. Since the Carroll group emerges as the isometry group of a class of plane gravitational waves, we discuss some specific examples, which we use in order to illustrate the so-called gravitational memory effect.
