Abstract
In this note we prove some universal algebraic properties of α-limits, and apply them to characterize a certain class of ∑-pure injective rings. This will provide an answer to a generalized version of a problem of Jensen and Lenzing. Our results also yield a module-theoretic characterization of singular cardinals.
