Contravariant and covariant indices

vendredi 28 février 2014

When we write contravariant and covariant indices, for example for the Lorentz transformation, does it matter if we write [itex] \Lambda^\mu\,_\nu [/itex] or [itex] \Lambda^\mu_\nu [/itex]?

i.e. if the [itex] \nu [/itex] index is to the right of the [itex]\mu[/itex] or they are at the same place with respect to left-right?
