Piotr Szewczyk
I am a Ph.D. student in the Institut für Algebra under the joint supervision of Arno Fehm and Sylvy Anscombe since April 2022. I am interested in the model theory of valued fields, particularly generalizations of the Ax-Kochen/Ershov property, characterizing class of extremal fields, and in understanding various types of defect extensions/defectless properties for valued fields. In my research, I am supported by the DFG in project 404427454.
