Conjecture Definition and 230 Threads

In mathematics, a conjecture is a conclusion or a proposition which is suspected to be true due to preliminary supporting evidence, but for which no proof or disproof has yet been found. Some conjectures, such as the Riemann hypothesis (still a conjecture) or Fermat's Last Theorem (a conjecture until proven in 1995 by Andrew Wiles), have shaped much of mathematical history as new areas of mathematics are developed in order to prove them.

    Grimm's Conjecture: Origin & Sources

    Can someone tell me when Grimm's conjecture (http://mathworld.wolfram.com/GrimmsConjecture.html) was formulated? I can't find any sources on that, and I don't have Guy's book.

    Is the Berry Operator the Key to Solving the Zeta Function?

    Is "Berry Operator"... H=-i\hbar(x\frac{d}{dx}+1/2) the operator which give all the solutions of \zeta(1/2+iE_{n})=0 ?..it seems too easy to be true...:eek: :eek:

    Euler product and Goldbach conjecture

    In an anlaogy with the Euler product of the Riemann function we make: \prod_{p}(1+e^{-sp})=f(s) of course we have that: f(p1+p2+p3)=f(p1)f(p2)f(p3) f(x)=exp(-ax) if Goldbach Conjecture is true then p1+p2= even and p5+p6+p8=Odd for integer n>5? then this product should be equal to...

    Triangular Number Conjecture: Recursive Series

    My question is...could the Hilbert-Polya conjecture if true prove RH (Riemann Hypothesis) i mean let,s suppose we find an operator ( i found a Hamiltonian with a real potential that gave all the roots of \zeta(1/2+is) ) in the form: R=1/2+iH with H self-adjoint so all the "eigenvalues"...

    Extension of Thurston's Geometrization Conjecture to four dimensions?

    The Existence of The Book: Paul Erdos's Conjecture

    According to this paper, http://arxiv.org/abs/math.GM/0108201 Paul Erdos (of Erdos number fame) conjectured the existence of The Book, a book that contains all the smallest proofs of mathematics arranged in lexical order. What are your thoughts on it, do you believe in the existence of such book?

    Has the Poincare Conjecture Finally Been Solved?

    Mathematicians are now saying that Grigory Perelman has really solved the conjecture and the proof will be in a paper he will post in the near future. His previous papers on this subject are in the arxiv specal topic Differential Geometry (under mathematics). Keep your eyes on this space!

    Difficulty with the Erdos-Straus Conjecture

    The Erdos-Straus Conjecture proposes that: For n >= 1, 4/n = 1/a + 1/b + 1/c, has postive integer solutions. n = 2k (evens) n = 4k+3 (odds) n = 4k+1 (odds) For 2k I have found the pattern --> if k >= 1, 4/2k = 1/2k + 1/2k + 1/k. This is simple, I know. I am having difficulty...
