Abstract
Let be a commutative noetherian local ring. We investigate under which conditions an -module is generated by an ideal , i.e. there exists an epimorphism . If is uniserial, i.e. is totally ordered and finite, this is equivalent to (). If is cyclic and , this is equivalent to: Either it is ( a discrete valuation ring) or ( a uniserial -module). If is free and is a submodule of , then the Matlis dual is -generated if and only if . In the case , this condition leads to the "basically full ideals" considered by Heinzer, Ratliff~Jr. and Rush. By studying the dual condition in the last section, we can generalize some results of that work.
