On the Waring-Goldbach problem on average

Let $s$, $\ell$ be two integers such that $2\le s\le \ell-1$, $\ell\ge 3$. We prove that a suitable asymptotic formula for the average number of representations of integers $n=\sum_{i=1}^{s} p_{i}^{\ell}$, where $p_i$, $i=1,\dotsc,s$, are prime numbers, holds in short intervals.

Exponential sums over primes in short intervals and an application to the Waring--Goldbach problem

Let $Λ(n)$ be the von Mangoldt function, $x$ real and $2\leq y \leq x$. This paper improves the estimate on the exponential sum over primes in short intervals \[ S_k(x,y;α) = \sum_{x< n \leq x+y} Λ(n) e\left( n^k α\right) \] when $k\geq 3$ for $α$ in the minor arcs. And then combined with the Hardy--Littlewood circle method, this enables us to investigate the Waring--Goldbach problem of representing a positive integer $n$ as the sum of $s$ $k$th powers of almost equal prime numbers, which improves the results in Wei and Wooley [12].

On the Waring-Goldbach Problem for One Square and Five Cubes

Let $\mathcal{P}_r$ denote an almost-prime with at most $r$ prime factors, counted according to multiplicity. In this paper, it is proved that for every sufficiently large even integer $N$, the equation \begin{equation*} N=x^2+p_1^3+p_2^3+p_3^3+p_4^3+p_5^3 \end{equation*} is solvable with $x$ being an almost-prime $\mathcal{P}_6$ and the other variables primes. This result constitutes an improvement upon that of Cai, who obtained the same conclusion, but with $\mathcal{P}_{36}$ in place of $\mathcal{P}_6$.

On the Waring-Goldbach problem with almost equal summands

We use transference principle to show that whenever $s$ is suitably large depending on $k \geq 2$, every sufficiently large natural number $n$ satisfying some congruence conditions can be written in the form $n = p_1^k + \dots + p_s^k$, where $p_1, \dots, p_s \in [x-x^θ, x + x^θ]$ are primes, $x = (n/s)^{1/k}$ and $θ= 0.525 + ε$. We also improve known results for $θ$ when $k \geq 2$ and $s \geq k^2 + k + 1$. For example when $k \geq 4$ and $s \geq k^2 + k + 1$ we have $θ= 0.55 + ε$. All previously known results on the problem had $θ> 3/4$.

This result constitutes an improvement upon that of Lü and Mu.

On Waring-Goldbach Problem for Squares, Cubes and Higher Powers

Let $\mathcal{P}_r$ denote an almost-prime with at most $r$ prime factors, counted according to multiplicity. In this paper, we generalize the result of Vaughan for ternary admissible exponent. Moreover, we use the refined admissible exponent to prove that, for $3\leqslant k\leqslant 14$ and for every sufficiently large even integer $n$, the following equation \begin{equation*} n=x^2+p_1^2+p_2^3+p_3^3+p_4^3+p_5^k \end{equation*} is solvable with $x$ being an almost-prime $\mathcal{P}_{r(k)}$ and the other variables primes, where $r(k)$ is defined in Theorem. This result constitutes a deepening…

Waring-Goldbach problem in short intervals

Let $k\geq2$ and $s$ be positive integers. Let $θ\in(0,1)$ be a real number. In this paper, we establish that if $s>k(k+1)$ and $θ>0.55$, then every sufficiently large natural number $n$, subjects to certain congruence conditions, can be written as $$ n=p_1^k+\cdots+p_s^k, $$ where $p_i(1\leq i\leq s)$ are primes in the interval $((\frac{n}{s})^{\frac{1}{k}}-n^{\fracθ{k}},(\frac{n}{s})^{\frac{1}{k}}+n^{\fracθ{k}}]$. The second result of this paper is to show that if $s>\frac{k(k+1)}{2}$ and $θ>0.55$, then almost all integers $n$, subject to certain congruence conditions, have above representat…

Discorrelation between primes in short intervals and polynomial phases

Let $H = N^θ, θ> 2/3$ and $k \geq 1$. We obtain estimates for the following exponential sum over primes in short intervals: \[ \sum_{N < n \leq N+H} Λ(n) e(g(n)), \] where $g$ is a polynomial of degree $k$. As a consequence of this in the special case $g(n) = αn^k$, we deduce a short interval version of the Waring-Goldbach problem.
