A result on Waring–Goldbach problem for cubes
Lithuanian Mathematical Journal, 2011Let \(N\) 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, 2019This 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, 2013Suppose 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.
