翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Quasi-isomorphism ： ウィキペディア英語版 Quasi-isomorphism In homological algebra, a branch of mathematics, a quasi-isomorphism is a morphism ''A'' → ''B'' of chain complexes (respectively, cochain complexes) such that the induced morphisms :$H\_n(A\_\backslash bullet)\; \backslash to\; H\_n(B\_\backslash bullet)\backslash \; (\backslash text\; H^n(A^\backslash bullet)\; \backslash to\; H^n(B^\backslash bullet))\backslash$ 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. ==References== *Gelfand, Manin. ''Methods of Homological Algebra'', 2nd ed.
