Recovering a covering of schemes from Galois orbits of power series
- Paul Helminck (University of Durham)
In this talk, I will give a general technique to find poset substructures of schemes using discrete Galois-data associated to coverings. In particular, this gives a fast algorithm to calculate dual intersection complexes of semistable models of varieties, provided a suitable covering is given. I will show how tropical geometry and schön compactifications of branch loci can be used to generate these coverings.
