WebThe Killing form and the Weyl group Lie algebras - basic notions A subspace h of a Lie algebra g, that is closed under the Lie bracket (i.e. [h;h] ˆh) is called a Lie subalgebra. De nition 1 A Lie subalgebra h is an ideal if [g;h] ˆh. 2 A Lie algebra g is abelian if [g;g] = 0. 3 A non-abelian Lie algebra g that does not contain any WebConsider the Killing form of the Lie algebra g l m. Then { e i j } is a basis for this Lie algebra where e i j is a matrix with 1 in the i th row, j th column and 0 everywhere else. Then every A = ( a i j) ∈ g l m can be written as A = ∑ i, j = 1 m a i j e i j.
