Archimedean specialization of Shelah's conjecture for NIP real fields
Archimedean specialization of Shelah's conjecture for NIP real fields
Let be an NIP real field, and suppose that admits at least one archimedean ordering.
Archimedean specialization of Shelah's conjecture. Then is real closed.
This is presented as a further specialization of the preceding conjecture: any henselian valuation on a real field is convex with respect to every ordering, so an archimedean ordering forces such a valuation to be trivial. The source does not specify whether this conjectural specialization has been resolved.
