Abstract

In this article, we study constrained minimizers of the following variational problem
e(ρ):=???20180223??? E(u), ρ > 0,
where E(u) is the Schrödinger-Poisson-Slater (SPS) energy functional
E(u):=1/2 ∫R3|▽u(x)|2dx -1/4 ∫R3R3 (u2|(y)u2(x))/(|x-y|)dydx -1/pR3|u(x)|pdx in R3,
and p ∈ (2, 6). We prove the existence of minimizers for the cases 2< p < 10/3, ρ > 0, and p=10/3, 0< ρ < ρ*, and show that e(ρ)=-∞ for the other cases, where ρ*=||φ||22 and φ(x) is the unique (up to translations) positive radially symmetric solution of -△u + u=u7/3 in R3. Moreover, when e(ρ*)=-∞, the blow-up behavior of minimizers as ρρ* is also analyzed rigorously.
