On the Waring–Goldbach problem for seventh and higher powers [PDF]

open access: yesMonatshefte Fur Mathematik, 2016
We apply recent progress on Vinogradov's mean value theorem to improve bounds for the function $H(k)$ in the Waring-Goldbach problem. We obtain new results for all exponents $k \ge 7$, and in particular establish that for large $k$ one has \[H(k)\le (4k ...

On the Waring--Goldbach problem for eighth and higher powers [PDF]

open access: yesJournal of the London Mathematical Society, 2015
Recent progress on Vinogradov's mean value theorem has resulted in improved estimates for exponential sums of Weyl type. We apply these new estimates to obtain sharper bounds for the function $H(k)$ in the Waring--Goldbach problem.

A note on the Waring–Goldbach problem

open access: yesJournal of Number Theory, 2010
For a positive integer \(k\) and a prime \(p\), let \(\nu_p(k)\) denote the \(p\)-adic valuation of \(k\), i.e., \(\nu_p(k)\) is the largest integer \(\nu\) such that \(p^{\nu} \mid k\). Let \(\gamma(k, p) = \nu_p(k)+1\) if either \(p\) or \(k\) is odd, and let \(\gamma(k, 2) = \nu_2(k)+2\) if \(k\) is even. For a positive integer \(k\), we define \(K =

Waring-Goldbach problem in short intervals

open access: yesIsrael Journal of Mathematics, 2019
Let $k\geq2$ and $s$ be positive integers. Let $\theta\in(0,1)$ be a real number. In this paper, we establish that if $s>k(k+1)$ and $\theta>0.55$, then every sufficiently large natural number $n$, subjects to certain congruence conditions, can be ...

On the Waring–Goldbach problem with small non-integer exponent [PDF]

open access: yesActa Arithmetica, 2003
Let \(c>1\) be non-integer and denote by \(H(c)\) the least \(k\) such that the inequality \[ |p_1^c + p_2^c + \cdots + p_k^c - N|< \varepsilon \] has a solution in prime numbers \(p_1, p_2, \ldots, p_k\) for every \(\varepsilon >0\) and \(N> N_0(c, \varepsilon)\). In 1952 \textit{I. I. Piatetski-Shapiro} [Mat. Sb., N. Ser.

ON THE WARING–GOLDBACH PROBLEM FOR CUBES [PDF]

open access: yesGlasgow Mathematical Journal, 2009
AbstractWe prove that almost all natural numbers satisfying certain necessary congruence conditions can be written as the sum of two cubes of primes and two cubes of P2-numbers, where, as usual, we call a natural number a P2-number when it is a prime or the product of two primes. From this result we also deduce that every sufficiently large integer can

On the Hybrid Power Mean of Two‐Term Exponential Sums and Cubic Gauss Sums

open access: yesJournal of Mathematics, Volume 2021, Issue 1, 2021., 2021
In this paper, an interesting third‐order linear recurrence formula is presented by using elementary and analytic methods. This formula is concerned with the calculating problem of the hybrid power mean of a certain two‐term exponential sums and the cubic Gauss sums.

Another Waring–Goldbach problem

open access: yesActa Arithmetica, 2023
In the paper under review, the author establishes a Waring-Goldbach analogue of a past result of C. Hooley. More specifically, \textit{C. Hooley} [Symp. Durham 1979, Vol. 1, 127--191 (1981; Zbl 0463.10037)] proved the theorem that for large \(n\), the Diophantine equation \[ x_1^2+x_2^2+x_3^3+x_4^4+x_5^5+x_6^6+x_7^7=n \tag{1} \] has solutions in non ...
