Abstract
In this article, we study the integral system involving the Riesz potentials
u(x) = √p ∫ℝn up-1(y)v(y)dy/|x-y|n-α, u > 0 in ℝn,
v(x) = √p ∫ℝn up(y)dy/|x-y|n-α v > 0 in ℝn,
where n ≥ 1, 0 < α < n and p > 1. Such a system is related to the study of a static Hartree equation and the Hardy-Littlewood-Sobolev inequality. We investigate the regularity of positive solutions and prove that some integrable solutions belong to C1(ℝn). An essential regularity lifting lemma comes into play, which was established by Chen, Li and Ma [20].
