On algebraically maximal valued fields that are not defectless

Commutative Algebra 2026-01-09 v1

Abstract

We use a known example of an algebraically maximal discretely valued field of positive characteristic pp which admits purely inseparable extensions of degree p2p^2 with defect pp to construct algebraically maximal valued fields of characteristic pp as well as of characteristic 00 and of rank 2 which admit separable extensions of degree p2p^2 with defect pp.
