TL;DR
This paper provides a new, characteristic-independent proof for characterizing bounded automorphisms of algebraically closed fields and extends the approach to fields with operators.
Contribution
It introduces a novel proof technique applicable across all characteristics and generalizes the characterization to fields with additional operators.
Findings
Alternative proof valid in all characteristics
Generalization to fields with operators
Characterization of bounded automorphisms
Abstract
We give an alternative proof, valid in all characteristics, of a result of Lascar characterising the bounded automorphisms of an algebraically closed field. We generalise this method to various fields equipped with operators.
