Abstract

Let FF be a field complete with respect to a discrete valuation whose residue field is perfect of characteristic p>0p>0. We prove that every smooth, projective, geometrically irreducible curve of genus one defined over FF with a non-zero divisor of degree a power of pp has a solvable point over FF. We also show that there is a field FF complete with respect to a discrete valuation whose residue field is perfect and there is a finite Galois extension KFK|F such that there is no solvable extension LFL|F such that the extension KLKKL|K is unramified, where KLKL is the composite of KK and LL. As an application we deduce that that there is a field FF as above and there is a smooth, projective, geometrically irreducible curve over FF which does not acquire semi-stable reduction over any solvable extension of FF.
