Abstract

Let R be a subring of the rational numbers ℚ. We recall from [3] that an R-module G is a splitter if Ext¹_R(G,G) = 0. In this note we correct the statement of Main Theorem 1.5 in [3] and discuss the existence of non-free splitters of cardinality ℵ₁under the negation of the special continuum hypothesis CH.
