In Euclidean SpaceTime, 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.
