Relative p-adic Hodge theory and Rapoport-Zink period domains
As an example of relative p-adic Hodge theory, we sketch the construction of
the universal admissible filtration of an isocrystal (\phi$-module) over the
completion of the maximal unramified extension of Q_p, together with the
associated universal crystalline local system.Comment: 20 page
Semistable reduction for overconvergent F-isocrystals, II: A valuation-theoretic approach
We introduce a valuation-theoretic approach to the problem of semistable
reduction (i.e., existence of logarithmic extensions on suitable covers) of
overconvergent isocrystals with Frobenius structure. The key tool is the
quasicompactness of the Riemann-Zariski space associated to the function field
of a variety.Comment: 20 pages; v3: refereed version; corrections to 4.2.1, 4.3.1; some
results extended to the partially overconvergent case (replacing Remark
