{"product_id":"unsolved-problems-in-number-theory-book-richard-k-guy-9780387942896","title":"Unsolved Problems in Number Theory","description":"Unsolved Problems in Number Theory contains discussions of hundreds of open questions, organized into 185 different topics. They represent numerous aspects of number theory and are organized into six categories: prime numbers, divisibility, additive number theory, Diophantine equations, sequences of integers, and miscellaneous. To prevent repetition of earlier efforts or duplication of previously known results, an extensive and up-to-date collection of references follows each problem. In the second edition, not only extensive new material has been added, but corrections and additions have been included throughout the book.","brand":"WoB","offers":[{"title":"US \/ GOOD \/ SBYB","offer_id":50160430350609,"sku":"CIN0387942890G","price":25.77,"currency_code":"USD","in_stock":false},{"title":"GB \/ VERY_GOOD \/ INTERNAL","offer_id":50561566179601,"sku":"GOR001901304","price":81.99,"currency_code":"USD","in_stock":true},{"title":"US \/ VERY_GOOD \/ SBYB","offer_id":51732378845457,"sku":"CIN0387942890VG","price":13.12,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/0387942890.jpg?v=1751166034","url":"https:\/\/www.worldofbooks.com\/products\/unsolved-problems-in-number-theory-book-richard-k-guy-9780387942896","provider":"World of Books ","version":"1.0","type":"link"}
