Abstract:In this paper we construct a ring A which has annihilator condition (a.c.) and we show that neither A[x] nor A[[x]] has this property. This answers in negative a question asked by Hong, Kim, Lee and Nielsen. We also show that there is an algebra A which does not have annihilator condition while both A[x] and A[[x]] have this property.
Keywords:16D25  16S36  Annihilator condition (a.c.)  Annihilators
