DESCRIPTION:Speakers: Guilherme Pimentel (Scuola Normale Superiore)\n\nI w
 ill review how a series of impressive numerical calculations in the early 
 90s provided evidence of universal scaling behavior in gravitational colla
 pse. Then I focus on the specific example of a spherically symmetric cloud
  of a perfect fluid. Using the inverse of the number of dimensions as a sm
 all parameter\, we found the critical solution and computed the universal 
 scaling behavior. At leading order\, it is independent of the equation of 
 state\, and reminiscent of mean field theory. This rich system provides ma
 ny potential routes for exploring universality in classical gravity\, with
  1/D playing a similar role as the epsilon expansion in statistical physic
 s. Based on a series of papers to appear with Craig R. Clark.\n \n\nhttps
