Euler's Sum of Powers Conjecture

Euler's Sum Of Powers Conjecture

Euler's conjecture is a disproved conjecture in mathematics related to Fermat's last theorem which was proposed by Leonhard Euler in 1769. It states that for all integers n and k greater than 1, if the sum of n kth powers of positive integers is itself a kth power, then n is greater than or equal to k.

In symbols, if \sum_{i=1}^{n} a_i^k = b^k where and are positive integers, then .

The conjecture represents an attempt to generalization of Fermat's last theorem, which could be seen as the special case of n = 2: if, then .

Although the conjecture holds for the case of k = 3 (which follows from Fermat's last theorem for the third powers), it was disproved for k = 4 and k = 5. It still remains unknown if the conjecture fails or holds for any value k ≥ 6.

Famous quotes containing the words sum, powers and/or conjecture:

    “The real risks for any artist are taken ... in pushing the work to the limits of what is possible, in the attempt to increase the sum of what it is possible to think. Books become good when they go to this edge and risk falling over it—when they endanger the artist by reason of what he has, or has not, artistically dared.”
    —Salman Rushdie (b. 1947)

    “... when I exclaim against novels, I mean when contrasted with those works which exercise the understanding and regulate the imagination.—For any kind of reading I think better than leaving a blank still a blank, because the mind must receive a degree of enlargement and obtain a little strength by a slight exertion of its thinking powers ...”
    —Mary Wollstonecraft (1759–1797)

    “What these perplexities of my uncle Toby were,—’tis impossible for you to guess;Mif you could,—I should blush ... as an author; inasmuch as I set no small store by myself upon this very account, that my reader has never yet been able to guess at any thing. And ... if I thought you was able to form the least ... conjecture to yourself, of what was to come in the next page,—I would tear it out of my book.”
    —Laurence Sterne (1713–1768)
