Question about the kinematic equation

  1. Mar 22, 2010 #1
    In Euclidean Space-Time, the kinematic equation is:
    am i correct if i write :
    [tex]K^{\mu \nu}_{\mu \nu}=g_{\mu \nu}x^{\mu}x^{\nu}[/tex]
    where [tex]s^2=K^{\mu \nu}_{\mu \nu}[/tex]?
    thank you very much

    You could, but why? You do understand that the repeated indices mean a sum over all mu and nu from 0 to 3.
