DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OLS/71/">Dec
 idability and definability in unramified henselian valued fields</a>\nby F
 ranziska Jahnke (University of Münster) as part of Online logic seminar\n
 \n\nAbstract\nUnramified and finitely ramified henselian valued fields are
 \ncentral to studying model-theoretic phenomena in mixed characteristic.\n
 Decidability and definability in unramified henselian valued fields with\n
 perfect residue field are well understood\, starting with the seminal\nwor
 k of Ax\, Kochen\, and Ershov. In this talk\, we present recent\ndevelopme
 nts in unramified henselian valued fields with imperfect\nresidue field\, 
 and also comment on what changes in the case of finite\nramification. This
  is joint work with Sylvy Anscombe.\n
