Specialization of Difference Equations and High Frobenius Powers

Yuval Dor, Ehud Hrushovski

We study valued fields equipped with an automorphism $I ¨ $ which is locally infinitely contracting in the sense that $I^\pm ≪ I ¨ I^\pm$ for all $0 < I^\pm \in I^$ . We show that various notions of…

Contracting Endomorphisms of Valued Fields

Yuval Dor, Yatir Halevi

We prove that the class of separably algebraically closed valued fields equipped with a distinguished Frobenius endomorphism $x \mapsto x^{q}$ is decidable, uniformly in $q$ . The res…
