WebAbstract. The Nagata-Higman theorem for the nilpotency of nil algebras of bounded index was proved in 1953 by Nagata [Nal] over a field of characteristic 0 and then in 1956 by Higman [Hg] in the general setup. Much later it was discovered that this theorem was first established in 1943 by Dubnov and Ivanov [DI] but their paper was overlooked by ...
