摘要:
We introduce the notion of a Richman extension of an integral domain, and show its basic properties. We further show that a flat extension need not be a Richman extension, and a Richman extension need not be an LCM-stable extension.

摘要:
In this paper we show that the kernel of the universal central extension of a crossed module in Lie algebras is the second invariant of this crossed module. As a consequence of this result we obtain a recognition criterion for universal central extensions and a vanishing situation of two invariants associated to a crossed module in Lie algebras.

摘要:
Let (R, m) be a two-dimensional regular local ring and letAbe a finitely generated torsion-freeR-module. IfAis a complete module, then Dan Katz and Vijay Kodiyalam showAsatisfies five conditions. They ask whether these five conditions are equivalent without assumingAto be complete. In a previous paper we determined all implications among these five conditions with one exception. In this paper, with an additional hypothesis on the units ofR, we resolve the remaining case.
