摘要
Let λ1,λ2,λ3,λ4 be non-zero real numbers, not all of the same sign, w real. Suppose that the ratios λ1/λ2,λ1/λ3 are irrational and algebraic. Then there are infinitely many solutions in primes pj, j = 1, 2,3,4, to the inequality |λ1p1 +λ2p^2/2 +λ3p^2/3+|λ4p^2/4+■(max{p1,p^2/2,p^2/3,p^2/4})-^5/64. This improves the earlier result.
