Just been reading on Christoffel Symbols and I am having a notational mind block.
Say we have:
[tex]\Gamma^{k}_{ij} v^{i} v^{j}[/tex]
The velocity depends on this expression, but I don't read this term [tex]v^{i} v^{j}[/tex] as a velocity squared do I? It's just the one velocity, are the superscripts here denoting different ''points''?
