چکیده

In this article a condition is given to detect the containment among thick subcategories of bounded derived category commutative noetherian ring. More precisely, for ring R R and complexes -modules with finitely generated homology M"> M encoding="application/x-tex">M N"> N encoding="application/x-tex">N , we show in subcategory by if only ghost index N Subscript German p"> p encoding="application/x-tex">N_\mathfrak {p} respect M encoding="application/x-tex">M_\mathfrak finite each prime alttext="German encoding="application/x-tex">\mathfrak . To do so, establish “converse coghost lemma” non-negatively graded DG algebra homology.

Classifying Subcategories of Modules over a Commutative Noetherian Ring

Abstract. Let R be a quotient ring of a commutative coherent regular ring by a finitely generated ideal. Hovey gave a bijection between the set of coherent subcategories of the category of finitely presented R-modules and the set of thick subcategories of the derived category of perfect R-complexes. Using this isomorphism, he proved that every coherent subcategory of finitely presented R-module...

CLASSIFYING COMPACTLY GENERATED t-STRUCTURES ON THE DERIVED CATEGORY OF A NOETHERIAN RING

We classify complactly generated t-structures on the derived category of modules over a commutative Noetherian ring R in terms of decreasing filtrations by supports on Spec(R). A decreasing filtration by supports φ : Z → Spec(R) satisfies the weak Cousin condition if for any integer i the set φ(i) contains all the inmediate generalizations of each point in φ(i+ 1). Every t-structure on Dbfg(R) ...

The Stable Derived Category of a Noetherian Scheme

For a noetherian scheme, we introduce its unbounded stable derived category. This leads to a recollement which reflects the passage from the bounded derived category of coherent sheaves to the quotient modulo the subcategory of perfect complexes. Some applications are included, for instance an analogue of maximal CohenMacaulay approximations, a construction of Tate cohomology, and an extension ...

The sum-annihilating essential ideal graph of a commutative ring

Let $R$ be a commutative ring with identity. An ideal $I$ of a ring $R$is called an annihilating ideal if there exists $rin Rsetminus {0}$ such that $Ir=(0)$ and an ideal $I$ of$R$ is called an essential ideal if $I$ has non-zero intersectionwith every other non-zero ideal of $R$. Thesum-annihilating essential ideal graph of $R$, denoted by $mathcal{AE}_R$, isa graph whose vertex set is the set...

The annihilator-inclusion Ideal graph of a commutative ring

Let R be a commutative ring with non-zero identity. The annihilator-inclusion ideal graph of R , denoted by ξR, is a graph whose vertex set is the of allnon-zero proper ideals of $R$ and two distinct vertices $I$ and $J$ are adjacentif and only if either Ann(I) ⊆ J or Ann(J) ⊆ I. In this paper, we investigate the basicproperties of the graph ξR. In particular, we showthat ξR is a connected grap...
