{"product_id":"9780486165677","title":"Real Analysis","description":"This text offers upper-level undergraduates and graduate students a survey of practical elements of real function theory, general topology, and functional analysis. Beginning with a brief discussion of proof and definition by mathematical induction, it freely uses these notions and techniques. The maximality principle is introduced early but used sparingly; an appendix provides a more thorough treatment. The notion of convergence is stated in basic form and presented initially in a general setting. The Lebesgue-Stieltjes integral is introduced in terms of the ideas of Daniell, measure-theoretic considerations playing only a secondary part. The final chapter, on function spaces and harmonic analysis, is deliberately accelerated. Helpful exercises appear throughout the text. 1959 edition.","brand":"Dover Publications","offers":[{"title":"Default Title","offer_id":47105148420336,"sku":"9780486165677","price":10.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9780486165677_p0.jpg?v=1763708510","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9780486165677","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
