Sur les automorphismes bornés de corps munis d'opérateurs
Submission date: 14 May 2015.
[In French, Work started during the programme Model Theory, Arithmetic Geometry and Number Theory, at MSRI on Spring 2014.]
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.
