Abstract In this paper, we introduce and investigate two weak versions of graded-Noetherian modules. Let G G be an abelian group with an identity element denoted by 0 0, R R be a commutative G G ...

I am confused about \bar {\rational}. It is a field and so has only maximal ideals; it is thus Noetherian as a ring. Rather, we are interested in an infinitely ascending chain of \rational-submodules ...

Abstract Let 𝑅 be a commutative Noetherian ring and let 𝒟(𝑅) be its (unbounded) derived category. We show that all compactly generated t-structures in 𝒟(𝑅) associated to a left bounded filtration ...

In this note we show that a Noetherian module has a dual module if and only if it satisfies $AB5^\ast$. A connection between completeness and $AB5^\ast$ is also ...
