Abstract: In [1], Gyamfi et al. described homological properties in relation to Nakayama Algebras with projectives that satisfied condition Extn Λ(M, N) = 0 for n ≫ 0 ⇐⇒ Extn Λ(N, M) = 0 for n ≫ 0, [1]. The purpose of this paper is to give a similar characterization of Nakayama algebras. In particular, we present Ext-groups of the Nakayama algebras with projectives that do not satisfy the condition Extn Λ(M, N) = 0 for n ≫ 0 ⇐⇒ Extn Λ(N, M) = 0 for n ≫ 0. To do this, we consider the Ext-groups of Nakayama algebra with projectives of lengths 3n and 4n using combinations of modules of different lengths.
