On the Waring-Goldbach problem for two squares and four cubes
Let NN be a sufficiently large integer. In this article, it is proved that, with at most O(N112+ε)O\left({N}^{\tfrac{1}{12}+\varepsilon }) exceptions, all even positive integers up to NN can be represented in the form p12+p22+p33+p43+p53+p63{p}_{1}^{2 ...

The Density of Rational Points on Non‐Singular Hypersurfaces, I [PDF]
For any n ⩾ 3, let F ∈ Z[X0, …, Xn] be a form of degree d ⩾ 5 that defines a non‐singular hypersurface X ⊂ Pn. The main result in this paper is a proof of the fact that the number N(F; B) of Q‐rational points on X which have height at most B satisfies N ...

Short intervals asymptotic formulae for binary problems with primes and powers, I: density 3/2 [PDF]
We prove that suitable asymptotic formulae in short intervals hold for the problems of representing an integer as a sum of a prime and a square, or a prime square.

A pair of equations in unlike powers of primes and powers of 2
In this article, we show that every pair of large even integers satisfying some necessary conditions can be represented in the form of a pair of one prime, one prime squares, two prime cubes, and 187 powers of 2.

Equal sums of like polynomials [PDF]
Let $f$ be a polynomial of degree $d>6$, with integer coefficients. Then the paucity of non-trivial positive integer solutions to the equation $f(a)+f(b)=f(c)+f(d)$ is established.

Quantitative relations between short intervals and exceptional sets of cubic Waring-Goldbach problem
In this paper, we are able to prove that almost all integers n satisfying some necessary congruence conditions are the sum of j almost equal prime cubes with j = 7, 8, i.e., N=p13+…+pj3$\begin{array}{} N=p_1^3+ \ldots +p_j^3 \end{array} $ with |pi−(N ...

Exceptional sets in Waring's problem: two squares and s biquadrates [PDF]
Let $R_s(n)$ denote the number of representations of the positive number $n$ as the sum of two squares and $s$ biquadrates. When $s=3$ or $4$, it is established that the anticipated asymptotic formula for $R_s(n)$ holds for all $n\le X$ with at most $O(X^

On pairs of equations in unlike powers of primes and powers of 2
In this paper, we obtained that when k = 455, every pair of large even integers satisfying some necessary conditions can be represented in the form of a pair of unlike powers of primes and k powers of 2.

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

On Waring's problem for intermediate powers [PDF]
Let $G(k)$ denote the least number $s$ such that every sufficiently large natural number is the sum of at most $s$ positive integral $k$th powers. We show that $G(7)\le 31$, $G(8)\le 39$, $G(9)\le 47$, $G(10)\le 55$, $G(11)\le 63$, $G(12)\le 72$, $G(13 ...
