Shock waves, part 3
In a previous post I wrote about shock waves in fluids, including the case that they are described by the Einstein-Euler equations for a self-gravitating fluid in general relativity. I mentioned
there a result of Fredrik Ståhl and myself proving that smooth solutions of the Einstein-Euler system can... | {"url":"http://alanrendall.wordpress.com/2010/04/06/shock-waves-part-3/","timestamp":"2014-04-20T08:15:26Z","content_type":null,"content_length":"49432","record_id":"<urn:uuid:197360c7-3a1b-453b-a39b-66e1487860ec>","cc-path":"CC-MAIN-2014-15/segments/1397609538110.1/warc/CC-MAIN-20140416005218-00322-ip-10-147-4-33.ec2.... |
