associator
Let be a non-associative algebra over a field. The associator of , denoted by , is a trilinear (http://planetmath.org/multilinear) map from to given by:
Just as the commutator measures how close an algebra is to being commutative, the associator measures how close it is to being associative. identically iff is associative.
