The most important property of the Kronecker delta occurs when it shares a common repeated index with another tensor: Note 10.1.3. When an index of a tensor T is contracted with one of the indices of the Kronecker delta, the result is an expression in which the Kronecker delta is removed and the contracted index of T is replaced by the other index of the Kronecker delta.
