On a diophantine inequality involving prime numbers of a special form

  • Yuhui Liu

摘要

Let N be a sufficiently large real number. In this paper, we prove that for \(2<c< \frac{68}{33}\) 2 < c < 68 33 and for any arbitrary large number \(E>0\) E > 0 , the Diophantine inequality \(\begin{aligned} \left| p_{1}^{c}+p_{2}^{c}+p_{3}^{c}+p_{4}^{c}+p_{5}^{c}-N\right| <\left( \log N\right) ^{-E} \end{aligned}\) p 1 c + p 2 c + p 3 c + p 4 c + p 5 c - N < log N - E is solvable in prime variables \(p_1,p_2,p_3,p_4,p_5\) p 1 , p 2 , p 3 , p 4 , p 5 such that, each of the numbers \(p_{i}+2\,\, (1\le i\le 5)\) p i + 2 ( 1 i 5 ) has at most \(\big [\frac{214467}{136000-66000c}\big ]\) [ 214467 136000 - 66000 c ] prime factors, counted with multiplicity.
