SUMMARY:Gerben Oling (U. Edinburgh) - 
DESCRIPTION:Speaker: Gerben Oling\n\nTitle: Carroll Gravity\, BKL Dynamics 
 and Holography\n\nAbstract: While Carroll geometry has exciting potential 
 applications in the context of flat space holography\, we can also conside
 r an ultra-local small-speed-of-light Carroll limits in gravity itself. At
  first\, this may seem like an esoteric thing to do\, compared to for exam
 ple the non-relativistic expansion of gravity. However\, as it turns out\,
  Carroll limits in GR lead to remarkable simplifications. In this talk\, I
  will connect these limits to BKL limits of gravity\, which similarly desc
 ribe solvable and rich dynamics\, in the vicinity of singularities. These 
 limits have recently reappeared in the context of AdS/CFT\, and I will rep
 roduce some of those models from matter-coupled Carroll gravity. Finally\,
  I will discuss some ongoing work on how Carroll limits of gravity can be 
 used to go beyond existing near-singularity limits.
