ANALOGY: This is an analogue in Lie ring of a property encountered in group. Specifically, it is a Lie subring property analogous to the subgroup property: characteristic direct factor

A subring of a Lie ring is termed a derivation-invariant direct factor if it is both derivation-invariant and a direct factor of the whole ring.
