Recent Progress on Definability of Henselian Valuations
Arno Fehm, Franziska Jahnke
Although the study of the definability of henselian valuations has a long history starting with J. Robinson, most of the results in this area were proven during the last few years.…

On the quantifier complexity of definable canonical henselian valuations
Arno Fehm, Franziska Jahnke
We discuss definability in the language of rings without parameters of the unique canonical henselian valuation of a field. We show that in most cases where the canonical henselian…

Fields with almost small absolute Galois group
Arno Fehm, Franziska Jahnke
We construct and study fields F with the property that F has infinitely many extensions of some fixed degree, but E*/(E*)^n is finite for every finite extension E of F and every n>…
