Hi,
I'm teaching myself tensor analysis and am worried about a notational device I can't find any explanation of (I'm primarily using the Jeevanjee and Renteln texts).
Given that the contravariant/covariant indices of a (1,1) tensor correspond to the row/column indices of its matrix representation, what is indicated by horizontally shifting one index with respect to the other? Is this notationally redundant, or is some extra information I'm missing being encoded here? Given that this convention also applies to (n,m) tensors and even the Kronecker delta, I want to clear this up before proceeding further.
