Hi all,(adsbygoogle = window.adsbygoogle || []).push({});

I have found the "generic" form of the FLRW metric:

[tex]ds^2=(cdt)^2-dl^2[/tex]

And I have found the three-dimension spatial metric for euclidian space (K=0, spherical space K=1 and hyperboloid space (K=-1):

[tex]dl^2=a^2(dr^2+r^2d\Omega^2)[/tex]

[tex]dl^2=a^2(\frac{dr^2}{1-r^2})+r^2d\Omega^2)[/tex]

[tex]dl^2=a^2(\frac{dr^2}{1+r^2})+r^2d\Omega^2)[/tex]

BUT how do I find the "general" form of the FLRW metric, how can I include the curvature parameter K?

Please help, I really need it!

Best regards.
