{"product_id":"9783034809504","title":"Module Theory, Extending Modules and Generalizations","description":"\u003cp\u003eThe main focus of this monograph is to offer a comprehensive presentation of known and new results on various generalizations of CS-modules and CS-rings. Extending (or CS) modules are generalizations of injective (and also semisimple or uniform) modules. While the theory of CS-modules is well documented in monographs and textbooks, results on generalized forms of the CS property as well as dual notions are far less present in the literature.\u003c\/p\u003e\u003cp\u003eWith their work the authors provide a solid background to module theory, accessible to anyone familiar with basic abstract algebra. The focus of the book is on direct sums of CS-modules and classes of modules related to CS-modules, such as relative (injective) ejective modules, (quasi) continuous modules, and lifting modules. In particular, matrix CS-rings are studied and clear proofs of fundamental decomposition results on CS-modules over commutative domains are given, thus complementing existing monographs in this area.\u003c\/p\u003e\u003cp\u003eOpen problems round out the work and establish the basis for further developments in the field. The main text is complemented by a wealth of examples and exercises.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e","brand":"Springer Basel","offers":[{"title":"Default Title","offer_id":47034940293360,"sku":"9783034809504","price":129.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9783034809504_p0.jpg?v=1763711414","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9783034809504","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
