Simply connected math
Webb1 feb. 2013 · By the purity theorem, U is simply connected. 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. Webb8 apr. 2024 · Simply-connected group.
