On a ternary diophantine inequality with prime numbers of a special type II

  • Li Zhu

摘要

Suppose that N is a sufficiently large real number and E is an arbitrarily large constant. In this paper, it is proved that, for \(1< c < \frac{7}{6}\) 1 < c < 7 6 , the Diophantine inequality \(\begin{aligned} |p_1^c+p_2^c+p_3^c-N|<(\log N)^{-E} \end{aligned}\) | p 1 c + p 2 c + p 3 c - N | < ( log N ) - E is solvable in prime variables \(p_1,p_2,p_3\) p 1 , p 2 , p 3 so that each of the numbers \(p_i+2,\,i=1,2,3\) p i + 2 , i = 1 , 2 , 3 , has at most \(\big [3.43655+{\frac{12.12}{7-6c}}\big ]\) [ 3.43655 + 12.12 7 - 6 c ] prime factors counted with multiplicity.
