Whitehead's theorem
The Whitehead Theorem is the name given to the following two theorems of algebraic topology , which go back to JHC Whitehead and are not related to one another :
- Every weak homotopy equivalence between CW complexes is a homotopy equivalence, see homotopy equivalence # Satz_von_Whitehead
- Every differentiable manifold is triangulable, see Triangulierbarkeit # Triangulierbarkeit_von_manifolds
