In Euclidean Space-Time, the kinematic equation is:
[tex]s^2=g_{\mu\nu}x^{\mu}x^{\nu}[/tex]
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.
