Moreover, in most stability theorems for functional equations, the completeness of the target space of the unknown functions contained in the equation is assumed. Recently, the question, whether the stability of a functional equation implies this completeness, has been investigated by several authors.\u003c\/p\u003e \u003cp\u003eIn this book the authors investigate these developments in the theory of approximate functional equations.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eA useful text for graduate seminars and of interest to a wide audience including mathematicians and applied researchers\u003c\/li\u003e\n\u003cli\u003ePresents recent developments in the theory of approximate functional equations\u003c\/li\u003e\n\u003cli\u003eDiscusses the stability problem of functional equations in Banach algebras, inner product spaces and amenable groups\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Elsevier Science","offers":[{"title":"Default Title","offer_id":47071304155376,"sku":"9780128039717","price":63.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9780128039717_p0.jpg?v=1763640921","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9780128039717","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
