Ok so this is a fairly stupid question I'm sure, but I'm not quite clear about the following:
Given a Lorentz transformation we require the following to hold:
[tex]g_{\sigma\rho}\Lambda^{\sigma}_{\mu}\Lambda^{\rho}_{\nu} = g_{\mu\nu}[/tex]
In other notation this is written:
[tex]\Lambda^{T}g\Lambda = g[/tex]
where [tex]\Lambda \in O(1,3)[/tex] and g is the Minkowski metric.
The first use of tensor notation is fine, however I am unsure why in the second expression the first [tex]\Lambda[/tex] is transposed?
Any help greatly appreciated,
Alex
