There, the bracket on the left side is the operation of the original algebra, the bracket on the right is the commutator of the composition of operators, and the identity states that the

The identity is named after the German mathematician 1769: 2882: 2120:
Another rearrangement shows that the Jacobi identity is equivalent to the following identity between the operators of the adjoint representation:

Notice the pattern in the variables on the left side of this identity. In each subsequent expression of the form

The following identity follows from anticommutativity and Jacobi identity and holds in arbitrary Lie algebra:

Thus, the Jacobi identity for Lie algebras states that the action of any element on the algebra is a
