Splitting fields of differential symbol algebras

Rings and Algebras 2024-04-04 v2

Abstract

For m2m\geq 2, we study derivations on symbol algebras of degree mm over fields with characteristic not dividing mm. A differential central simple algebra over a field kk is split by a finitely generated extension of kk. For certain derivations on symbol algebras, we provide explicit construction of differential splitting fields and give bounds on their algebraic and transcendence degrees. We further analyze maximal subfields that split certain differential symbol algebras.
