S-divisible modules over domains.
An extension of integral domains is strongly-compatible (resp., -compatible) if (resp., for every nonzero finitely generated fractional ideal of . We show that strongly -compatible implies -compatible and give examples to show that the converse does not hold. We also indicate situations where strong -compatibility and its variants show up naturally. In addition, we study integral domains such that is strongly -compatible (resp., -compatible) for every overring of .
