Orbits of a Killing vector field

  1. Mar 12, 2012 #1
    I was wondering what the orbits of a Killing vector field are. Do you have any good sources or reading material for this?

    Given a (not necessarily Killing) vector field [itex]V^\mu(x)[/itex], its "orbits" are solutions [itex]Z^\mu(\lambda)[/itex] to the differential equation [itex]\dot{Z}^\mu(\lambda) = V^\mu(Z(\lambda))[/itex], where the dot is a [itex]\lambda[/itex] derivative. Intuitively, an orbit just "follows the little arrows of the vector field".

    That's all there is to it.

    Thanks Sam. I'll do some calculations with this definition and come back if I have further clarifications.

    Hall's book on symmetries in GR is my favorite, I'd go so far as to say, I love it.
