Left invariant derivations #
In this file we define the concept of left invariant derivation for a Lie group. The concept is analogous to the more classical concept of left invariant vector fields, and it holds that the derivation associated to a vector field is left invariant iff the field is.
Moreover we prove that left_invariant_derivation I G has the structure of a Lie algebra, hence
implementing one of the possible definitions of the Lie algebra attached to a Lie group.

Left-invariant global derivations.
A global derivation is left-invariant if it is equal to its pullback along left multiplication by
an arbitrary element of G.
