Lie submodules of a Lie algebra #

In this file we define Lie submodules and Lie ideals, we construct the lattice structure on Lie submodules and we use it to define various important operations, notably the Lie span of a subset of a Lie module.

structure LieSubmodule (R : Type u) (L : Type v) (M : Type w) [CommRing R] [LieRing L] [AddCommGroup M] [Module R M] [LieRingModule L M] extends Submodule :

A Lie submodule of a Lie module is a submodule that is closed under the Lie bracket. This is a sufficient condition for the subset itself to form a Lie module.

                                A morphism of Lie algebras f : L → L' pushes forward Lie ideals of L to Lie ideals of L'.

                                Note that unlike LieSubmodule.map, we must take the lieSpan of the image. Mathematically this is because although f makes L' into a Lie module over L, in general the L submodules of L' are not the same as the ideals of L'.

                                  Note that f makes L' into a Lie module over L (turning f into a morphism of Lie modules) and so this is a special case of LieSubmodule.comap but we do not exploit this fact.
