Abstrakt: An archimedean ℓ-group is called epicomplete (or universally σ- complete, or sequentially inextensible) if it is divisible, σ-complete and laterally σ-complete. Various characterizations of such G are known in case the G have weak order units. The “theorem” of the title is a characterization of such G which have no weak order unit; it involves the requirement that G have a certain kind of representation. The “question” of the title is whether every epicomplete G has such a representation. [ABSTRACT FROM AUTHOR]
