报 告 摘 要

The talk revisits the classical Matlis duality for modules over commutative ringswhich gives rise to the notion of Matlis reflexivity. It turns out that Matlis reflexivemodules form a Krull-Schmidt category. For noetherian rings the absence of infinitedirect sums is a characteristic feature of Matlis reflexivity. This leads to a discussionof objects that are extensions of artinian by noethenian objects.
