DESCRIPTION:Eugene Lim\nCollisions of solitons and domain walls are often 
 very messy affairs and require numerical approaches. However\, I will show
  that such collisions in the ultra-relativistic limit possess a well-defin
 ed perturbative approach\, with an expansion in the powers of inverse Lore
 ntz factor times the inverse velocity. This allows us to attack these prob
 lems analytically without the use of numerics. As a demonstration\, I will
  derive the velocity and phase shifts in the collisions of solitons with p
 eriodic but non-integrable potentials.\nIf we have time\, I will also show
  some cool movies from GRCHOMBO\, a new numerical relativity code with ada
 ptive mesh refinement!
