... map is surjective. The Poincar´e-Birkhoff-Witt theorem asserts that w : SL → gr UL is an isomorphism. (1.19) Supp ose that we choose a basis x i , i ∈ I of L where I is a totally ordered set. Since (x i )(x j ) ... the composition  M ◦ h : L → UM induces a homomorphism UL → UM and this assignment sending Lie algebra homomorphisms into associative algebra homomorphisms is functorial. 1.8.6...

... open sets is dense. Thus Baire s theorem asserts that every complete metric space is a Baire space. A set A in a topological space is called nowhere dense if its closure contains no open set. ... distance from A is a closed set. It clearly is a closed set which contains A. Suppose that S is some closed set containing A, and y ∈ S. Then there is some r > 0 such that B r (y) is containe...
