The famous 3n+1 conjecture, which remains open, states that, for any starting number n\u0026gt;0, iterated application of T to n eventually produces 1. After a survey of theorems concerning the 3n+1 problem, the main focus of the book are 3n+1 predecessor sets. These are analyzed using, e.g., elementary number theory, combinatorics, asymptotic analysis, and abstract measure theory. The book is written for any mathematician interested in the 3n+1 problem, and in the wealth of mathematical ideas employed to attack it.\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783540639701\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783540639701","offer_id":39427410264157,"sku":"9783540639701","price":42.79,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/07cade2f-6f5c-44c1-beb4-65bf63fb0a18.jpg?v=1772084384","url":"https:\/\/shop.autorenwelt.de\/en\/products\/the-dynamical-system-generated-by-the-3n-1-function-von-gunther-j-wirsching","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
