The local refined Oort conjecture for cyclic extensions
The local refined Oort conjecture for cyclic extensions
Let be the residue field of a discrete valuation ring of characteristic zero, and let be a cyclic -extension with Galois sub-extension . Suppose is a lift of the sub-extension. The local refined Oort conjecture. There exist a finite extension of and a -Galois extension that lifts and contains as a sub-extension. By a local-to-global principle, this local assertion is sufficient for the global refined Oort conjecture and concerns extending a prescribed local lift through a cyclic Galois extension.
