Ternary commutator explained
In mathematical physics, the ternary commutator is an additional ternary operation on a triple system defined by
[a,b,c]=abc-acb-bac+bca+cab-cba.
Also called the
ternutator or
alternating ternary sum, it is a special case of the
n-commutator for
n = 3, whereas the 2-commutator is the ordinary
commutator.
Properties
- When one or more of a, b, c is equal to 0, [''a'', ''b'', ''c''] is also 0. This statement makes 0 the absorbing element of the ternary commutator.
- The same happens when a = b = c.
