A result on Waring–Goldbach problem for cubes

Lithuanian Mathematical Journal, 2011
Let \(N\) be a large number and \(4 \leq s \leq8\). Let \(E_s(N)\) denote the number of positive integers \(n \leq N\) which cannot be written in the form \[ n = m^3 + p_2^3 +p_3^3 + \cdots + p_s^3, \] with positive integer \(m\) and primes \(p_2, p_3, \ldots , p_s\).

The Waring–Goldbach problem for cubes with an almost prime

Proceedings of the London Mathematical Society, 2019
This paper shows that every sufficiently large even integer \(N\) can be written in the form \[N=p_1^3+\ldots+p_7^3+x^3\] with \(x\) being the product of two distinct primes. Previously it had been shown by \textit{J. Brüdern} [Ann. Sci. Éc. Norm. Supér. (4) 28, No. 4, 461--476 (1995; Zbl 0839.11045)] that one could handle such representations with \(x\

The Waring–Goldbach problem: one square and five cubes

The Ramanujan Journal, 2013
Suppose that \(p_1, p_2, p_3, p_4, p_5\) are prime numbers and a natural number \(x\) has at most 36 prime factors, counted according to multiplicity. Let \(R(N)\) denote the number of solutions of the following equation \[ N=x^2+p_1^3+p_2^3+p_3^3+p_4^3+p_5^3.
