Cauchy surface

  1. Jul 20, 2010 #1
    Is a null hyperplane a Cauchy surface in Minkowski spacetime?
    What in case of other spacetimes?

    This is something that you should try to work through. What is a Cauchy surface? A readable definition is given on pages 79-80 of Sean Carroll's book An Introduction to General Relativity: Spacetime Geometry. This is just one example of where Carroll's book is better than Carroll'a arXiv notes.
    I am not sure what you're asking.
