Ok, so I know we have some math and physics folk here, so I was wondering if someone could help me with this. Apparently, any isotropic function v has the relation below (where the symbol on the right is the Kronecker delta). I need to prove this relation. Does anyone have any ideas? Anyone seen or used this relation before?
