本文研究了以下l2 -临界最小化问题的约束最小化:e(N):=inf{e(u),u∈H1(R3)和∫R3|u|2dx=N>},其中ee (u)是Schrödinger‐Poisson‐Slater泛函e(u):=∫R3|∇u|2dx−12∫R3∫R3u2(y)u2(x)|x−y|dydx−35∫R3m(x)|u|103dx, N表示Schrödinger‐Poisson‐Slater系统中粒子的质量。我们证明了(N)对于and有极小值,然而,对于N>N *没有极小值,其中q (x)是in的唯一正解。给出了(N *)前最小值的存在性和不存在性的一些结果。此外,当(N∗)不允许最小值时,也严格地分析了最小值asN * N *的极限行为。
In this paper, we study constraint minimizers of the followingL2−critical minimization problem: e(N):=inf{E(u),u∈H1(R3)and∫R3|u|2dx=N>0}, whereE(u) is the Schrödinger‐Poisson‐Slater functional E(u):=∫R3|∇u|2dx−12∫R3∫R3u2(y)u2(x)|x−y|dydx−35∫R3m(x)|u|103dx, andNdenotes the mass of the particles in the Schrödinger‐Poisson‐Slater system. We prove thate(N) admits minimizers forand, however, no minimizers forN>N∗, whereQ(x) is the unique positive solution ofin. Some results on the existence and nonexistence of minimizers fore(N∗) are also established. Further, whene(N∗) does not admit minimizers, the limit behavior of minimizers asN↗N∗is also analyzed rigorously.
