## Main Question or Discussion Point

Hi.

I came across the following statement , which seems wrong to me.

Λ

I have it on good authority (a previous post on this forum) that (Λ

The equation Λ

Why is one of the Lorentz matrices transposed ? It looks like it should be Λ η Λ = η

Thanks

I came across the following statement , which seems wrong to me.

Λ

^{μ}_{ρ}= ( Λ^{T})_{ρ}^{μ}I have it on good authority (a previous post on this forum) that (Λ

^{T})^{μ}_{ν}= Λ^{ν}_{μ}so I am hoping that the first equation is wrong ? It looks like the inverse not the transpose ?The equation Λ

^{μ}_{ρ}η_{μν}Λ^{ν}_{σ}= η_{ρσ}is written in matrix form as Λ^{T}η Λ = ηWhy is one of the Lorentz matrices transposed ? It looks like it should be Λ η Λ = η

Thanks
