## Exceptional set of a representation with fractional powers

Acta Mathematica Hungarica
Authors:
E. Balanzario
,
M. Garaev
, and
R. Zuazua

## Abstract

We prove that for any given c, 1 < c < 17/11, almost all natural numbers are representable in the form [x c] + [p c], where x is a natural number and p is a prime.

## Hua’s theorem with nine almost equal prime variables

Acta Mathematica Hungarica
Authors:
G. Lü
and
Y. Xu

## Abstract

We sharpen Hua’s result by proving that each sufficiently large odd integer N can be written as

, where p j are primes. This result is as good as what was previously derived from the Generalized Riemann Hypothesis.

## Sums of almost equal prime cubes

Acta Mathematica Hungarica
Author:
F. Zhao

## Abstract

We prove that almost all integers N satisfying some necessary congruence conditions are the sum of j almost equal prime cubes with j = 5; 6; 7; 8, i.e., N = p 1 3 + ... + p j 3 with |p i − (N/j)1/3| ≦

## Additive bases arising from functions in a Hardy field

Acta Mathematica Hungarica
Authors:
T. H. Chan
,
A. V. Kumchev
, and
M. Wierdl

## Abstract

A classical additive basis question is Waring’s problem. It has been extended to integer polynomial and non-integer power sequences. In this paper, we will consider a wider class of functions, namely functions from a Hardy field, and show that they are asymptotic bases.

## An improvement on Waring–Goldbach problem for unlike powers

Acta Mathematica Hungarica
Author:
Zhixin Liu

## Abstract

Let p i be prime numbers. In this paper, it is proved that for any integer k≧5, with at most exceptions, all positive even integers up to N can be expressed in the form . This improves the result for some c>0 due to Lu and Shan [12], and it is a generalization for a series of results of Ren and Tsang [15], [16] and Bauer [1–4] for the problem in the form . This method can also be used for some other similar forms.

## On a generalization of Hua’s theorem with five squares of primes

Authors:

## Abstract

We sharpen Hua’s theorem with five squares of primes by proving that every sufficiently large integer N congruent to 5 modulo 24 can be written in the form
