Discuss Article Conjecture In mathematics , a conjecture is a mathematical statement which has been proposed as a true statement, but which no one has yet been able to prove or disprove. Once a conjecture has been proven, it becomes known as a theorem , and it joins the realm of known mathematical facts. Until that point in time, mathematicians must be extremely careful about their use of a conjecture within logical structures. Conjectural means presumed to be real, true, or genuine, mostly based on inconclusive grounds (cf. hypothetical ). The term was used by Karl Popper , in the context of scientific philosophy. Table of contents 1 Famous conjectures 2 Counterexamples 3 Use of conjectures in conditional proofs 4 Undecidable conjectures Famous conjectures Until its proof in 1995, the most famous of all conjectures was the mis-named Fermat's Last Theorem - this conjecture only became a true theorem after its proof. In the process, a special case of the Taniyama-Shimura conjecture , itself a longstanding open problem, was proven; this conjecture has since been completely proven.

CALL FOR OPEN PROBLEMS COLT 2007 will include a session devoted to the presentation of open problems. A description of these problems will also appear in the COLT proceedings. The write-up of an open problem should include the following: A clear, self-contained description of an open problem; Motivation for the study of this problem; The current state of understanding for this problem, including known partial solutions and citations of related published work. This year we also encourage people to propose descriptions of new interesting research directions in areas that are currently outside the scope of COLT, such as bioinformatics, privacy and security, and vision, to name a few. Ideally, your open problems or research directions should include well-defined mathematical questions, nontrivial, and explainable without requiring too much specialized background knowledge in a 5-10 minutes talk. A reward for solving an open problem is encouraged but not required. Format and submission details are as follows: The open problems should be 1-2 pages long in the COLT proceedings format. Please submit them electronically to

It is common in graduate schools to point out open problems to students. These students as well as faculty members engage in research to solve such problems. Examples of problems that have been closed, or solved, by faculty members in the late twentieth century are Fermat's last theorem and the Four color theorem." edit More Information List of unsolved problems at http://en.wikipedia.org/wiki/List_of_unsolved_problems

Number Theory : Open Problems ABC Conjecture We define the radical R(n) of an integer n to be the the product of its distinct prime divisors. ABC Conjecture: For every k>1, there is a constant C k such that if a,b,c are coprime positive integers satisfying a+b=c, then c < C k R(abc) k The conjecture was proposed by Osterle and Masser in 1985. At present the best that can be proved is that c < exp(R(abc)^f) for a suitable f. Mason has proved the analogue of the conjecture for polynomials. If true, the conjecture would have numerous important consequences: among them would be another proof of Fermat's Last Theorem. We define the ABC ratio for a triple (a,b,c) to be A = log(c) / log(R(abc)). The conjecture implies that A is bounded, so it is of interest to find large values of A. The current best is: a=2, b=3 .109, c=23 giving A = 1.6299 Collatz Problem Also known as the 3n+1 problem, Syracuse problem, Thwaites problem. Define a function on positive integers n -> 3n+1 if n is odd, n/2 is n is even. Does every positive integer eventually end up in the cycle 4 -> 2 -> 1 -> 4?
