So any étale covering of X is generically trivial (because its pullback on U is trivial), hence trivial since X is normal. In fact, this proves that if X and Y (both proper and normal) are birationally equivalent, and Y is regular and simply connected, then X is simply connected. WebbAn irrotational vector field is necessarily conservative provided that the domain is simply connected.

WebbCorollary 1.4 (Generalized Cauchy Integral formulas) Assume f ∈ Cω(D) and D ⊂ C simply connected, and δD = γ. For all n ∈ N one has f(n)(z) ∈ Cω(D) and for any z /∈ γ f(n)(z) = n! 2πi Z γ f(w) dz (w −z)n+1 Proof. Just diﬀerentiate Cauchy’s integral formula n times. It follows that f ∈ Cω(D) is arbitrary often diﬀerentiable. http://www.map.mpim-bonn.mpg.de/5-manifolds:_1-connected how does jumping a car workWebb107 Likes, 2 Comments - 80 Acres Farms (@80acresfarms) on Instagram: "STEM/STEAM day!

And since Xis path-connected, all constant maps to Xare homotopic. Conversely, if all maps S1→ Xare homotopic, then in particular the constant maps are homotopic, so X is path-connected.
