WebIn particular, we show that for each prime p ≥ 5, there are families of tamely ramified covers with monodromy the symmetric group S n or alternating group A n for infinitely many n. These covers come from the moduli spaces of elliptic curves with PSL 2 ( ℓ )-structure, and the analysis uses work of Bourgain, Gamburd, and Sarnak, and adapts ... WebThis removes the assumption in [LLHLM18,LLHLM20] that the representation be tamely ramified at p. We also prove a version of Breuil's lattice conjecture and a mod p multiplicity one result for the cohomology of U(3)-arithmetic manifolds. The key input is a study of the geometry of the Emerton-Gee stacks using the local models introduced in ... Webis a tamely ramified Galois extension of K with Galois group G, A is the group ring KG, and H = RG: then S is locally free of rank one as an RG-module: this is a theorem of Emmy Noether from the 1930's. For Galois extensions of local fields which are wildly ramified (i.e. not tamely ramified), S is not a free RG-module, and the structure of S as fb lb-105

WebFeb 9, 2024 · Unramified or tamely ramified extensions are usually much easier to study than wildly ramified extensions. In the unramified case, it results from the fact that G K / I K ≅ G k ⁢ (K) ≅ ℤ ^ is pro-cyclic. Thus an unramified representation is completely determined by the action of ρ ⁢ (σ) for a topological generator σ of G K / I K.

WebMay 1, 2024 · The extension F / K is tame since it is Galois of degree p − 1 and is ramified only at prime ideals lying above p; similarly E / L is tame. If L / K is tame then since E / L is tame we have that E / K is tame, and so E / F is tame. Conversely, if E / F is tame then since F / K is tame we have that E / K is tame, and so L / K is tame.
