{"product_id":"9780080887203","title":"Theory of Linear Operations","description":"This classic work by the late Stefan Banach has been translated into English so as to reach a yet wider audience. It contains the basics of the algebra of operators, concentrating on the study of linear operators, which corresponds to that of the linear forms a\u003cinf\u003e1\u003c\/inf\u003ex\u003cinf\u003e1\u003c\/inf\u003e + a\u003cinf\u003e2\u003c\/inf\u003ex\u003cinf\u003e2\u003c\/inf\u003e + ... + a\u003cinf\u003en\u003c\/inf\u003ex\u003cinf\u003en\u003c\/inf\u003e of algebra.\u003cbr\u003e\u003cbr\u003eThe book gathers results concerning linear operators defined in general spaces of a certain kind, principally in Banach spaces, examples of which are: the space of continuous functions, that of the p\u003csup\u003eth\u003c\/sup\u003e-power-summable functions, Hilbert space, etc. The general theorems are interpreted in various mathematical areas, such as group theory, differential equations, integral equations, equations with infinitely many unknowns, functions of a real variable, summation methods and orthogonal series.\u003cbr\u003e\u003cbr\u003eA new fifty-page section (''Some Aspects of the Present Theory of Banach Spaces'') complements this important monograph.\u003cbr\u003e\u003cbr\u003e","brand":"Elsevier Science","offers":[{"title":"Default Title","offer_id":47108268785904,"sku":"9780080887203","price":72.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9780080887203_p0.jpg?v=1763637880","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9780080887203","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
