Title |
Tame ramification and compatible ideals |
Abstract |
We introduce a notion of tame ramification for general finite covers. When specialized to the separable case, it extends to higher dimensions the classical notion of tame ramification for Dedekind domains and curves. However, when applied to the Frobenius map, it naturally yields the notion of compatible ideals, which lets us describe how these behave under finite covers -it all comes down to a transitivity property for tame ramification in towers. This is joint work with Javier Carvajal-Rojas |
