Help required with notation.

  1. Dec 28, 2014 #1
    During my reading I met with,

    -1)μν = Λνμ ≡ ημρΛρσησν.

    Is it correct to say that η raises and lowers the indices of Λ giving Λμν, which, in turn, will give (Λ-1)μν = Λμν?

    Thanks for any help.

    The indices are not balanced. Check again the exact positioning.

    Thanks Dextercioby for your help.
    Does that mean that there is a misprint in what I read and the μ and the ν of the η must be exchanged?
