Répartition des points rationnels sur la cubique de Segre

We study the distribution of rational points on Segre's cubic defined as the locus of points x ∈ ℙ 5 such that{x 1 3 + x 2 3 + x 3 3 + x 4 3 + x 5 3 + x 6 3 = 0 ,x 1 + x 2 + x 3 + x 4 + x 5 + x 6 = 0 .In particular, we verify Manin's conjecture concerning the asymptotic behaviour of the number of non‐trivial rational points of height at most B .
