Wikipedia

  1. quism

    In homological algebra, a branch of mathematics, a quasi-isomorphism or quism is a morphism A → B of chain complexes (respectively, cochain complexes) such that the induced morphisms H n ( A ∙ ) → H n ( B ∙ ) ( respectively, H n ( A ∙ ) → H n ( B ∙ ) ) {\displaystyle H_{n}(A_{\bullet })\to H_{n}(B_{\bullet })\ ({\text{respectively, }}H^{n}(A^{\bullet })\to H^{n}(B^{\bullet }))} of homology groups (respectively, of cohomology groups) are isomorphisms for all n. In the theory of model categories, quasi-isomorphisms are sometimes used as the class of weak equivalences when the objects of the category are chain or cochain complexes. This results in a homology-local theory, in the sense of Bousfield localization in homotopy theory.
