Smooth submersion
Web24 Jan 2013 · In Lee's Introduction to smooth manifolds he states that given smooth manifolds X, Y and a surjective submersion, f: X → Y, then f is a smoothly final map, that is for any further smooth manifold Z, and any map g: Y → Z, we have g smooth if g ∘ f is smooth. He then says that problem 4.7 shows why this property is 'characteristic'.

D = [2x 2y 0 0; 2x 2y+1 2s 2t] the reduced row echelon form of D is a rank 2 matrix which implies that F is a smooth submersion. So I guess I'm a little confused on the definition: Let M and N be smooth manifolds. If F:M→N is smooth and let p M, then p is a regular point if D at p is onto.
WebIn mathematics, Sard's theorem, also known as Sard's lemma or the Morse–Sard theorem, is a result in mathematical analysis that asserts that the set of critical values (that is, the image of the set of critical points) of a smooth function f from one Euclidean space or manifold to another is a null set, i.e., it has Lebesgue measure 0.
