WebAn index that is not summed over is a free index and should appear only once per term. If such an index does appear, it usually also appears in every other term in an equation. An example of a free index is the "i " in the equation =, which is equivalent to the equation = (). Application. Einstein notation can be applied in slightly different ways.
