Gorenstein 投射模的单项射范畴及其与矩阵分解范畴的比较

表示论 2024-06-06 v3

摘要

设 (S,n)S, \mathfrak{n}) 为交换诺特局部环,ωn\omega\in\mathfrak{n} 为非零因子。本文研究有限生成 Gorenstein 投射 SS-模之间的单项射(monomorphisms)构成的范畴,要求其 cokernel 被 ω\omega 零化。我们将观察到,该范畴(记为 Mon(ω,G)(\omega,\mathcal{G}))在 Quillen 意义下是一个正合范畴。更一般地,证明了 Mon(ω,G)(\omega,\mathcal{G}) 是一个 Frobenius 范畴。令人惊讶的是,不仅矩阵分解范畴可以嵌入到 Mon(ω,G)(\omega,\mathcal{G}) 中,而且其稳定范畴以及因子环 R=S/(ω)R = S/(\omega) 的奇点范畴,均可实现为 Mon(ω,G)(\omega,\mathcal{G}) 稳定范畴的三角子范畴。
