In some cases, the Tor functor can be inconsistent with other operations defined on a set. For instance, consider a module M over a commutative ring and a submodule of M, N. The Tor functor is defined as the cokernel of a map defined from the tensor

The injective stabilization of the tensor product is subjected to an iterative procedure that utilizes its bifunctor property. The limit of this procedure, called the asymptotic stabilization of the tensor product, provides a homological counterpart

This paper presents a sound and complete sequent-style deduction system for determining behavioural equivalence in coalgebras of finitary set functors preserving weak pullbacks. We also prove soundness without the weak pullback requirement. Finitary

We lift to equivariant algebra three closely related classical algebraic concepts: abelian group objects in augmented commutative algebras, derivations, and Kahler differentials. We define Mackey functor objects in the category of Tambara functors au

For two classes of right R-modules W, X such that P ⊂ W ⊂ X, where P is the class of projective right R-modules, we show that there is an Avramov–Martsinkovsky type exact sequence with generalized Tate homology functor $${\widehat {Tor}^{X.W}}$

In this paper, we show that the higher derived functors of the primitive element functor of $$E_*(M)$$ where M is a quasitoric manifold and E is a complex-orientable homology theory are independent of the torus action, implying they depend on the orb

In this paper, we investigate the homological properties of the functor categories (mod−R, Ab) and ((mod−R)op, Ab). Some new homological dimensions in these functor categories such as FP-projecive dimensions and cotorsion dimensions for functors

Let R be a ring. Then a left R-module N is pure-injective if and only if HomR(M,N) is a pure-injective left S-module for any ring S and any (R,S)-bimodule RMS. If R is a commutative ring and M,N are R-modules with N pure-injective, then ExtRn(M,N) is

We introduce and study the relative left derived functor Torn(F,F′)(−,−) in the module category, which unifies several related left derived functors. Then we give some criteria for computing the F-resolution dimensions of modules in terms of th
