  2. Pólya conjecture - Wikipedia

    en.wikipedia.org/wiki/Pólya_conjecture

    The Pólya conjecture was disproved by C. Brian Haselgrove in 1958. He showed that the conjecture has a counterexample, which he estimated to be around 1.845 × 10 361. [3] A (much smaller) explicit counterexample, of n = 906,180,359 was given by R. Sherman Lehman in 1960; [4] the smallest counterexample is n = 906,150,257, found by Minoru ...

  3. Pólya enumeration theorem - Wikipedia

    en.wikipedia.org/wiki/Pólya_enumeration_theorem

    The Polya enumeration theorem translates the recursive structure of rooted ternary trees into a functional equation for the generating function F(t) of rooted ternary trees by number of nodes. This is achieved by "coloring" the three children with rooted ternary trees, weighted by node number, so that the color generating function is given by f ...

  4. Hilbert–Pólya conjecture - Wikipedia

    en.wikipedia.org/wiki/Hilbert–Pólya_conjecture

    The earliest published statement of the conjecture seems to be in Montgomery (1973). [1] [2] David Hilbert did not work in the central areas of analytic number theory, but his name has become known for the Hilbert–Pólya conjecture due to a story told by Ernst Hellinger, a student of Hilbert, to André Weil. Hellinger said that Hilbert ...

    [4]: 23–24 The specific topics treated bear witness to the special interests of Pólya (Descartes' rule of signs, Pólya's enumeration theorem), Szegö (polynomials, trigonometric polynomials, and his own work in orthogonal polynomials) and sometimes both (the zeros of polynomials and analytic functions, complex analysis in general).

    As reformulated, it became the "paving conjecture" for Euclidean spaces, and then a question on random polynomials, in which latter form it was solved affirmatively. 2015: Jean Bourgain, Ciprian Demeter, and Larry Guth: Main conjecture in Vinogradov's mean-value theorem: analytic number theory: Bourgain–Demeter–Guth theorem, ⇐ decoupling ...

    Colin Brian Haselgrove (26 September 1926 – 27 May 1964) was an English mathematician who is best known for his disproof of the Pólya conjecture in 1958. [1] Haselgrove was educated at Blundell's School and from there won a scholarship to King's College, Cambridge. He obtained his Ph.D., which was supervised by Albert Ingham, from Cambridge ...

  9. Möbius function - Wikipedia

    Other applications of () in combinatorics are connected with the use of the Pólya enumeration theorem in combinatorial groups and combinatorial enumerations. There is a formula [7] for calculating the Möbius function without directly knowing the factorization of its argument:
