SUMMARY:John Anderson - Formation of shocks for the Einstein-Euler system
LOCATION:Hill 705
DESCRIPTION:John Anderson – Stanford\nDate/Time/Location\n Thursday, November 2nd, 12:0
 0pm; Hill Center 705\n  Formation of shocks for the Einstein-Euler system\n
 In this talk, I hope to describe elements of proving a certain stable singu
 larity formation result for the Einstein-Euler system, which is the topic o
 f work in progress with Jonathan Luk. I'll first describe where this fits i
 nto 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 desc
 ribe some of the main ideas that go into proving shock formation, and the m
 ain difficulty in the case of Einstein-Euler. In a nutshell, the difficulty
  arises from the fact that the speed of sound is less than the speed of lig
 ht. In the remaining time, I will describe how this is related to shocks fo
 r other hyperbolic PDEs arising in continuum mechanics.\n
