SUMMARY:Impulsive gravitational waves
LOCATION:Hill Center Room 705
DESCRIPTION:Abstract: In a 1972 influential paper, Penrose introduced the concept of an
  impulsive gravitational wave, defined as a localized and singular solution
  of the Einstein equations. This is a model for the spacetime distortions c
 reated by a strongly gravitating source such as, say, a black hole merger. 
 An abundant literature, both in Physics and Mathematics, has since built up
  on Penrose’s work, with a particular interest in the interaction of severa
 l impulsive gravitational waves. The understanding was, until recently, how
 ever, limited to binary interactions. I will review these works and finish 
 with a new theory (obtained with jointly with J. Luk) that also allows for 
 ternary interactions of such impulsive gravitational waves under translatio
 n symmetry.\n
