Integers that are sums of two rational sixth powers

چکیده

Abstract We prove that $164\, 634\, 913$ is the smallest positive integer a sum of two rational sixth powers, but not powers. If $C_{k}$ curve $x^{6} + y^{6} = k$ , we use existence morphisms from to elliptic curves, together with Mordell–Weil sieve, rule out points on for various k .

On powers that are sums of consecutive like powers

1 Background The problem of cubes that are sums of consecutive cubes goes back to Euler ([10] art. 249) who noted the remarkable relation 33 + 43 + 53 = 63. Similar problems were considered by several mathematicians during the nineteenth and early twentieth century as surveyed in Dickson’sHistory of the Theory of Numbers ([7] p. 582–588). These questions are still of interest today. For example...

Perfect Powers That Are Sums of Consecutive Cubes

Euler noted the relation 63= 33+43+53 and asked for other instances of cubes that are sums of consecutive cubes. Similar problems have been studied by Cunningham, Catalan, Gennochi, Lucas, Pagliani, Cassels, Uchiyama, Stroeker and Zhongfeng Zhang. In particular, Stroeker determined all squares that can be written as a sum of at most 50 consecutive cubes. We generalize Stroeker’s work by determi...

q-ANALOGUES OF THE SUMS OF POWERS OF CONSECUTIVE INTEGERS

Let n, k be the positive integers (k > 1), and let Sn,q(k) be the sums of the n-th powers of positive q-integers up to k − 1: Sn,q(k) = ∑k−1 l=0 ql. Following an idea due to J. Bernoulli, we explore a formula for Sn,q(k).

Explicit Polynomial for Sums of Powers of Odd Integers

In this note we derive the explicit, non-recursive form of the coefficients of the polynomial associated with the sums of powers of the first n odd integers. As a by-product, we deduce a couple of new identities involving the Bernoulli numbers. Mathematics Subject Classification: 11B57, 11C08, 11B68

Linear algebra and the sums of powers of integers

A general framework based on linear algebra is presented to obtain old and new polynomial expressions for the sums of powers of integers. This framework uses changes of polynomial basis, infinite lower triangular matrices and finite differences.
