Characteristic derivation-invariant Lie subring
This page describes a Lie subring property obtained as a conjunction (AND) of two (or more) more fundamental subgroup properties: characteristic subring of a Lie ring and derivation-invariant Lie subring

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 subgroup

A subring of a Lie ring is termed a characteristic derivation-invariant Lie subring if it is both a characteristic subring (i.e., it is invariant under all automorphisms of the Lie ring) and a derivation-invariant Lie subring (i.e., it is invariant under all derivations of the Lie ring).
