Description |
Let $X$ be a scheme over a field $k$ amd $f:Y\to x$ an essentially finite morphism. We construct a `Galois closure' of $f$, i.e, the smallest possible torsor dominating it. As an application we construct the Galois closure of towers of torsors. (Work in collaboration with Michel Emsalem). |
