... Higher Rank Tensors Notice that our vector components A µ have one index, whereas a scalar (e.g. t = time or T = temperature) has zero indices. Thus scalars are called tensors of rank zero and ... as matrices. Higher rank tensors can be constructed from lower rank ones by forming what is called the outer product or tensor product [14] as follows. For instance T α β ≡ A α B β (3.17) or T αβ γδ...

Orthonormal ... the observer’s 4-velocity, gives an orthonormal basis or tetrad. Thus, an observer carries along an orthonormal bases that we call the observer’s tetrad. This basis is the natural one for splitt...
