Resumen de A result of Tosio Aoki about a generalization of Hyers�Ulam stability of additive functions � a question of priority
In 1940 Ulam proposed the well-known stability problem. In 1941 Hyers solved this problem for additive mappings. In 1950 Aoki proved a more general result, which was rediscovered again in 1978 by Rassias, and from then it is called by some authors the Hyers�Ulam�Rassias (HUR) stability theorem. We show here that, in fact, this theorem merits the name Hyers�Ulam�Aoki (HUA) stability theorem.
