(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

B is a third order tensor. Show that [itex]B^{ij}_{i}[/itex] is a contravariant vector.

3. The attempt at a solution

Well... I just thought about a simple solution but I don't think I'm right. But anyways.

Considering [itex]B^{ij}_{i}[/itex]. If I raise the index i: [itex]g^{ij}B^{ij}_{i} = B^{ijj}[/itex]

And so I can say that B is a first order tensor = vector. And this is a contravariant vector.

Is this right?
