Homework Help: Question on the notaion used to define Lie Derviative

  1. Sep 25, 2010 #1
    I have a definition of the Lie derivative, that is the one found here: http://planetmath.org/encyclopedia/LieDerivative2.html [Broken]

    However, I'm not sure what the notation [tex]Y_{\theta_t(p)}[/tex] used in that article means.

    Y is a vector field and [tex]\theta_t(p)[/tex] is a function. Does it mean evaluate Y at \theta_t(p)}[/tex]?

    Can someone explain.

    Yes. Your guess is good and it is consistent with the notation used throughout this article.
