For QTAG-modules the concept of quasi-isomorphism was defined by Mehdi [5]. Two QTAG-modules are quasi-isomorphic when they contain cobounded submodules. Here we prove that cobounded submodules inherit basic submodules. Then we impose some restrictions on quasi-isomorphism and find that quasi...

On quasi isomorphic QTAG-modules D. O. Cutler [Pac. J. Math. 16, 25-45 (1966; Zbl 0136.28904)] defined quasi-isomorphism for primary Abelian groups and studied the properties shared by quasi-isomorphic groups. P. Hill [Pac. J. Math. 22, 257-265 (1967; Zbl 0168.27303)] f... F ...
quasi-isomorphismThis paper investigates to which extent a self-small mixed Abelian group G of finite torsion-free rank is determined by the groups Hom(G,C) where C is chosen from a suitable class of Abelian groups. We show that G is determined up to quasi-isomorphism if is the class of...

;证明Tor symmetric, 对原projective resolution 取cone X, 为了对X tensor这个resolution, 把tensor的finite projective resolution看成是从这个resolution拆出来两个complex的morphism的cone, 把cone X即complex代入到这个cone中, 对dimension of finite complex作induction, 得到quasi-isomorphism, i.e. Hn() equals3....

quasi-isomorphismsIn this paper, we introduce the notion of Reidemeister torsion for quasi-isomorphisms of based chain complexes over a field. We call a chain map a quasi-isomorphism if its induced homomorphism between homology is an isomorphism. Our notion of torsion generalizes the torsion of ...
