,7. Kapitel Völkerschlachtdenkmal,We prove that every ∑-pure-injective module over a serial ring is serial and every ∑-pure-injective faithful indecomposable module over a serial ring is ∑-injective. Moreover, every serial ring that can be realized as the endomorphism ring of an artinian module has finite Krull dimension.

It also played a most important role in analysis and topology, for example in Banach spaces and algebraic topology. In algebra, beginning with the duality of finite abelian groups as well as that of finite dimensional vector spaces, its role has been no le
