# Unsolved problems in number theory download (a) When {ai}i is the sequence of primes. (c) {ai}i is anyone of the well known sequences of positive integers, for example Fibonacci (or Lucas, Fermat, Bernoulli, Mersenne, Smarandache, van der Waerden, etc.) numbers. UNSOLVED PROBLEM: Let k be a non-zero integer. Unsolved Problems in Number Theory may refer to: Unsolved problems in mathematics in the field of number theory. Goldbach's conjecture. Any even number can be written as a sum of two primes. Examples: 12 = 5 + 7. 28 = 5 + 23 = 11 +

Turn on 1-Click ordering. Mathematics is kept alive by the appearance of new, unsolved problems. This book provides a steady supply of easily understood, if not easily solved, problems that can be considered in varying depths by mathematicians at all levels of mathematical maturity. To many laymen, mathematicians appear to be problem solvers, people who do " hard sums". Even inside the profession we dassify ouselves as either theorists. Mathematics is kept alive by the appearance of new unsolved problems, problems posed from within mathematics itself, and also from the increasing number of.

A problem I particularly like is Broccard's problem. There are lots of Unsolved problems in number theory and some of them are not paid. Overview: This is a web site for amateurs interested in unsolved problems in number theory, logic, and cryptography. Please read the FAQ. How to use the site . One problem which I think is mentioned in Guy's book is the integer .. There is a lot of number theory elementary conjectures, but one that is.
