...way to write this concisely is by using the alternating symbol e^ 425 which is defined to be equal to 1 if ijk is an even permutation of 123, -1 if ijk is an odd permutation of 123, and zero if any two of ijk are equal. Using this notation, and the Einstein summation convention (where... | |

...introduce the permutation symbol e¿¿b also called the alternating symbol or the alternator, defined by {1 if (ijk) is an even permutation of (123). -1 if (ijk) is an odd permutation of (123), 0 otherwise, ie, if two subscripts are repeated. From this definition it follows that €jjk = -Cijy... | |
