Curves Which Do Not Become Semi-stable after Any Solvable Extension
We show that there is a field F complete with respect to a discrete valuation whose residue field is perfect and there is a finite Galois extension K|F such that there is no solvable Galois extension L|F such that the extension KL|K is unramified, where KL is the composite of K and L. As an application we deduce that that there is a field F as above and there is a smooth, projective, geometrica...
متن کاملSemi-stable Reduction for Curves
Given a normal proper and geometrically connected curve C over the function field K(S) of S, we seek “good” models over S. For instance, if we choose a projective embedding of C into some PK(S) then its Zariski closure in PS is an arithmetic surface (where the S-flatness uses that S is Dedekind). Hence, we can always find an arithmetic surface with generic fiber C. Since S is normal and C is re...
متن کاملLog smooth extension of family of curves and semi-stable reduction
Summery: We show that a family of smooth stable curves defined on the interior of a log regular scheme is extended to a log smooth scheme over the whole log regular scheme, if it is so at each generic point of the boundary, under a very mild assumption. We also include a proof of the fact that a log smooth scheme over a discrete valuation ring has potentially a semi-stable model. As a consequen...
متن کاملDo people become healthier after being promoted?
This paper examines the hypothesis that greater job status makes a person healthier. It begins by successfully replicating the well-known cross-section association between health and job seniority. Then, however, it turns to longitudinal patterns. Worryingly for the hypothesis, the data-on a large sample of randomly selected British workers through time-suggest that people who start with good h...
متن کاملMonodromy of stable curves of compact type: rigidity and extension
Let M̃g,n, for 2g − 2 + n > 0, be the moduli stack of n-pointed, genus g, stable curves of compact type. For a family C → S of such curves over a connected base and a geometric point ξ on S, the associated monodromy representation is the induced homomorphism π1(S, ξ) → π1(M̃g,n, [Cξ ]) on algebraic fundamental groups. We say that the family C → S is antilinear if its moduli only depend on the non...
