Add to ORKGA bounded automorphism of a field or a group with trivial approximate centre is definable. In an expansion of a field by a Pfaffian family F of additive endomorphisms such that algebraic closure in the expansion coincides with relative field-algebraic closure of the F-substructure generated, a bounded endomorphism, possibly composed with a power of the Frobenius, is a composition of endomorphisms associated with F.Un automorphisme borné d'un corps ou d'un groupe de centre approximatif trivial est définissable. Dans une expansion d'un corps par une famille F Pfaffienne d'endomorphismes additifs tel que la clôture algébrique dans l'expansion coïncide avec la clôture algébrique (corpique) relative de la F-sous-structure engendré, un endomorp...
