Heath-Brown–Moroz constant

The Heath-Brown–Moroz constant C, named for Roger Heath-Brown and Boris Moroz, is defined as

$C=\prod _p{(1-\frac{1}{p})}^7(1+\frac{7p+1}{p^2})=0.001317641...$

where p runs over the primes.

Application

This constant is part of an asymptotic estimate for the distribution of rational points of bounded height on the cubic surface X₀³=X₁X₂X₃. Let H be a positive real number and N(H) the number of solutions to the equation X₀³=X₁X₂X₃ with all the X_i non-negative integers less than or equal to H and their greatest common divisor equal to 1. Then

$N(H)=C\cdot \frac{H(\log H{)}^6}{4\times 6!}+O(H(\log H{)}^5).$
