Field patching, factorization and local-global principles

Daniel Krashen

Published 2009-09-16, updated 2009-12-15Version 2

In this paper we first describe the method of field patching, developed by Harbater and Hartmann, paying special attention to the relationship between factorization and local-global principles, and second, we extend the basic factorization result previously known for rational groups to the case of retract rational groups.
