Metric Tensors

  1. Jul 2, 2013 #1
    If I have a 4x4 Covarient Metric Tensor [tex]g_{ik}[/tex].

    I can find the determinant:

    [tex]G = det(g_{ik})[/tex]

    How do I find the 4x4 Cofactor of g_ik?
    [tex]G^{ik} [/tex]

    then [tex]g^{ik}=G^{ik}/G[/tex]

    This is just standard matrix inversion. Quoting from the Wikipedia page on "minors",
