Definition
A Lie ring is a set G equipped with the structure of an Abelian group (operation denoted + ) and a bracket operation
(called a Lie bracket) such that:
- Left and right distributivity laws hold, viz.:
[x,y + z] = [x,y] + [x,z]
and:
[x + y,z] = [x,z] + [y,z]
- The Lie bracket is anticommutative, viz., the following two laws hold:
[x,x] = 0
and:
[x,y] + [y,x] = 0
- The Lie bracket satisfies the Jacobi identity:
[[x,y],z] + [[y,z],x] + [[z,x],y] = 0
A Lie ring which is also an algebra over a field is termed a Lie algebra.
