Abstract
A ringR is called anAE n -ring,n≥2 a positive integer, if every endomorphism ϕ of additive group ofR satisfies ϕ(a 1 a 2...a n )=ϕ(a 1)ϕ(a 2)...ϕ(a n ) for alla 1,...,a n eR. Several results concerning the structure ofAE n -rings are obtained in this note, including an (incomplete) description ofAE n -ringsR satisfyingR t R n−1 ≠0, whereR t is the torsion ideal inR.
