Example Sentences
- "The Kronecker delta #92;delta#95;#123;ij#125; is an example of an isotropic tensor. That is, its components remain invariant with rotation of coordinate axes."
- "The permutation symbol and the Kronecker delta prove to be very useful in proving vector identities."
- "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."
