{"product_id":"9783034803137","title":"Homological Algebra of Semimodules and Semicontramodules: Semi-infinite Homological Algebra of Associative Algebraic Structures","description":"\u003cp\u003eThis is a monograph in semi-infinite homological algebra, concentrated mostly on the semi-infinite theory of associative algebraic structures, but including also some material on the semi-infinite homology and cohomology of Lie algebras and topological groups. The main objects of study are the double-sided derived functors SemiExt and SemiTor, and the phenomenon of comodule-contramodule correspondence, connecting them with the more conventional, one-sided Ext and CtrTor. Contramodules, introduced originally by Eilenberg and Moore in 1960's but almost forgotten for four decades, play a very prominent role in this book, with many versions of them introduced and discussed. Among other topics considered in the monograph there are the semi-infinite model category structures and the relative nohomogeneous Koszul duality.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e","brand":"Springer Basel","offers":[{"title":"Default Title","offer_id":47034931478768,"sku":"9783034803137","price":122.18,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9783034803137_p0.jpg?v=1763711829","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9783034803137","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
