Category of n -weak injective and n -weak flat modules with respect to special super presented modules [PDF]
Communications in Algebra, 2021 Let $R$ be a ring and $n$, $k$ two non-negative integers. In this paper, we introduce the concepts of $n$-weak injective and $n$-weak flat modules and via the notion of special super finitely presented modules, we obtain some characterizations of these modules. We also investigate two classes of modules with richer contents, namely $\mathcal{WI}_k^n(R)$

Remarks on Gorenstein Weak Injective and Weak Flat Modules [PDF]
Algebra Colloquium, 2020 In this paper, we introduce Gorenstein weak injective and weak flat modules in terms of, respectively, weak injective and weak flat modules; the classes of Gorenstein weak injective and weak flat modules are larger than the classical classes of Gorenstein injective and flat modules. In this new setting, we characterize rings over which all modules are

Higher topological Hochschild homology of periodic complex K-theory [PDF]
, 2020 We describe the topological Hochschild homology of the periodic complex $K$-theory spectrum, $THH(KU)$, as a commutative $KU$-algebra: it is equivalent to $KU[K(\mathbb{Z},3)]$ and to $F(\Sigma KU_{\mathbb{Q}})$, where $F$ is the free commutative $KU ...

Gorenstein \(n\)-weak injective and Gorenstein \(n\)-weak flat modules under excellent extensions
Journal of Mahani Mathematical Research, 2023 Summary: Let \(R\) be an associative ring and let \(n\) be a non-negative integer. In this paper, we consider \(n\)-super finitely presented, Gorenstein \(n\)-weak injective and Gorenstein \(n\)-weak flat modules under change of rings. For an excellent extension \(S\geq R\), we show that the Gorenstein \(n\)-super finitely presented dimensions (resp ...

The generating hypothesis in the derived category of a ring [PDF]
, 2006 We show that a strong form (the fully faithful version) of the generating hypothesis, introduced by Freyd in algebraic topology, holds in the derived category of a ring R if and only if R is von Neumann regular. This extends results of the second author.

Smashing localizations of rings of weak global dimension at most one [PDF]
, 2016 none2siWe show for a ring R of weak global dimension at most one that there is a bijection between the smashing subcategories of its derived category and the equivalence classes of homological epimorphisms starting in R. If, moreover, R is commutative,

Hochschild (co)homology of the second kind I [PDF]
, 2011 We define and study the Hochschild (co)homology of the second kind (known also as the Borel-Moore Hochschild homology and the compactly supported Hochschild cohomology) for curved DG-categories.

Homotopical Algebraic Context over Differential Operators [PDF]
, 2017 Building on previous works, we show that the category of non-negatively graded chain complexes of $D_X$-modules -- where $X$ is a smooth affine algebraic variety over an algebraically closed field of characteristic zero -- fits into a homotopical ...
