    The proof takes about 500 pages spread over about 20 papers. 2005 Kepler conjecture. Hales's proof of this involves several hundred pages of published arguments, together with several gigabytes of computer calculations. 2006 the strong perfect graph theorem, by Maria Chudnovsky, Neil Robertson, Paul Seymour, and Robin Thomas.

    Gauss produced two other proofs in 1816 and another incomplete version of his original proof in 1849. The first textbook containing a proof of the theorem was Cauchy's Cours d'analyse de l'École Royale Polytechnique (1821). It contained Argand's proof, although Argand is not credited for it. None of the proofs mentioned so far is constructive

    Mathematical chemistry [1] is the area of research engaged in novel applications of mathematics to chemistry; it concerns itself principally with the mathematical modeling of chemical phenomena. [2] Mathematical chemistry has also sometimes been called computer chemistry , but should not be confused with computational chemistry .

    The fact that a complex solution always exists is the fundamental theorem of algebra, which was proved only at the beginning of the 19th century and does not have a purely algebraic proof. Nevertheless, the main concern of the algebraists was to solve in terms of radicals , that is to express the solutions by a formula which is built with the ...

    In other words, the cardinality of the set of transcendentals (denoted ) is greater than that of the set of algebraic numbers (). [ 24 ] Bernhard Riemann , at the end of his famous 1859 paper " On the Number of Primes Less Than a Given Magnitude ", stated (based on his results) that the logarithmic integral gives a somewhat too high estimate of ...

    en.wikipedia.org/wiki/Abel–Ruffini_theorem

    The proofs based on Galois theory comprise four main steps: the characterization of solvable equations in terms of field theory; the use of the Galois correspondence between subfields of a given field and the subgroups of its Galois group for expressing this characterization in terms of solvable groups; the proof that the symmetric group is not ...
