Lie algebra extension of this expression. It is, using , identically zero. Hence the rhs of this expression is independent of and equals its value for , which is the lhs of this expression. If , then , acting by , is a derivation. The set is the set of inner derivations on . For finite-dimensional simple Lie algebras all derivations are inner derivations. Consider two Lie groups and and , the automorphism group of . The latter is the group of isomorphisms of . If there is a Lie group homomorphism , then for each there is a with the property .
