SUMMARY: Formation of shocks for the Einstein-Euler system -- John Anderson 
LOCATION: Hill 705
DESCRIPTION:<p>In this talk, I hope to describe elements of proving a certain stable si
 ngularity formation result for the Einstein-Euler system, which is the topi
 c of work in progress with Jonathan Luk. I'll first describe where this fit
 s into the big picture of the study of multidimensional shocks, and why it 
 is appropriate to call this a shock formation result. Then, I will try to d
 escribe some of the main ideas that go into proving shock formation, and th
 e main difficulty in the case of Einstein-Euler. In a nutshell, the difficu
 lty arises from the fact that the speed of sound is less than the speed of 
 light. In the remaining time, I will describe how this is related to shocks
  for other hyperbolic PDEs arising in continuum mechanics.</p>
