Dicle Mutlu Sozer (University of Leeds) – Types and Definable Groups in Henselian Valued Fields

Henselian valued fields have a central place in model theory: they provide natural examples of tame theories in the sense of classification theory, while also offering a rich setting in which to study complexity phenomena in model theory. In this talk, I will survey some fundamental model-theoretic results on Henselian valued fields and present new results from joint work with Paul Wang, in which we generalize results from the algebraically closed valued field setting to the broader Henselian context.
