{"product_id":"functional-equations-and-inequalities-in-stefan-czerwik-9789810248376","title":"Functional Equations and Inequalities in Several Variables","description":"This book outlines the modern theory of functional equations and inequalities in several variables. It consists of three parts. The first is devoted to additive and convex functions defined on linear spaces with semilinear topologies. In the second part, the problems of stability of functional equations in the sense of Ulam-Hyers-Rassias and in some function spaces are considered. In the last part, the functional equations in set-valued functions are dealt with -- for the first time in the mathematical literature. The book contains many fresh results concerning those problems.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Stefan Czerwik\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 9810248377\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9789810248376\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e World Scientific Publishing Company\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 05\/15\/2002\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 420\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Hardcover\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 1.55lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.10h x 6.20w x 0.90d","brand":"Stefan Czerwik","offers":[{"title":"Hardcover","offer_id":48448104759551,"sku":"9789810248376","price":151.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_d49e4cdb-9e52-4bf3-b5d3-7183babd500f.jpg?v=1777236924","url":"https:\/\/www.whiterainbookhouse.com\/products\/functional-equations-and-inequalities-in-stefan-czerwik-9789810248376","provider":"WR Book House","version":"1.0","type":"link"}
