Abstract: | In this note, we introduce a weak form of equational compactness of modules, which we called x
0-compactness, together with some of its basic properties. We then use it to settle in the negative a problem of G. H. Wenzel.
We also prove the adjacent result that, over a wide class of commutative rings, if every module is x
0-compact then the ring has finite representation type.
