The ramification-jump lifting conjecture for non-abelian cyclic p-Sylow groups
Let ppp be a prime, let GeZ/pnrtimesmathbbZ/mG e \mathbb{Z}/p^nrtimesmathbb{Z}/mGeZ/pnrtimesmathbbZ/m be non-abelian with pnmidmpnmid mpnmidm, and let k[[z]]/k[[t]]k[[z]]/k[[t]]k[[z]]/k[[t]] be a local GGG-extension whose Z/pn\mathbb{Z}/p^nZ/pn-subextension has…
