The quadratic Waring–Goldbach problem
The purpose of this paper is to show a new bound for the number \(E(N)\), say, of the natural numbers \(n\) such that \(n\leq N\), \(n\equiv4\pmod {24}\), and \(n\) cannot be written as the sum of four squares of primes. Actually, the authors establish the bound \(E(N)\ll N^{3/8+\varepsilon}\) with any fixed \(\varepsilon>0\). The proof is based on the

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.

On Sums of Powers of Almost Equal Primes [PDF]
We investigate the Waring-Goldbach problem of representing a positive integer $n$ as the sum of $s$ $k$th powers of almost equal prime numbers. Define $s_k=2k(k-1)$ when $k\ge 3$, and put $s_2=6$.

Relations between exceptional sets for additive problems [PDF]
We describe a method for bounding the set of exceptional integers not represented by a given additive form in terms of the exceptional set corresponding to a subform. Illustrating our ideas with examples stemming from Waring's problem for cubes, we show,

On Waring–Goldbach problem of mixed powers
Let 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 odd integer N, the equationN=x2+p13+p23+p33+p43+p56+p67is solvable with x being an almost-prime P 42 and the other terms powers of primes.

Sum of one prime and two squares of primes in short intervals [PDF]
Assuming the Riemann Hypothesis we prove that the interval $[N, N + H]$ contains an integer which is a sum of a prime and two squares of primes provided that $H \ge C (\log N)^{4}$, where $C > 0$ is an effective constant.Comment: removed unconditional ...

Linnik's approximation to Goldbach's conjecture, and other problems
We examine the problem of writing every sufficiently large even number as the sum of two primes and at most $K$ powers of 2. We outline an approach that only just falls short of improving the current bounds on $K$.

Estimates are provided for $s$th moments of cubic smooth Weyl sums, when $4\le s\le 8$, by enhancing the author's iterative method that delivers estimates beyond classical convexity.

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^
