双余模的伪对偶化复形与t-结构对

范畴论 2022-02-24 v6 环与代数

摘要

本文是arXiv:1703.04266的余代数版本,也是arXiv:1607.03066的续篇。我们给出了一对余结合余代数C\mathcal CD\mathcal D上的双余模的伪对偶化复形之定义。对任意这样的复形L\mathcal L^\bullet,我们构造一个三角范畴,其装备有一对(可能退化的)导出型t-结构,其心脏分别是左C\mathcal C-余模与左D\mathcal D-反余模的阿贝尔范畴。我们也考虑了由阿贝尔/正合范畴中具足够同伦调整复形的(余)消解子范畴所产生的伪导出范畴的弱版本。作为预备材料,我们讨论了余代数、余模与反余模的拟有限性条件。
