英文摘要 | In this paper, we study minimizers of the Hartree-type energy functional E-a(u) := integral N-R(vertical bar Delta u(x)vertical bar(2) + V(x)vertical bar u(x)vertical bar(2))dx - a/p integral N-R(I-alpha*vertical bar u(x)vertical bar(p)vertical bar u(x)vertical bar(p))dx, a >= 0 under the mass constraint integral N-R(vertical bar u vertical bar(2)dx = 1, where p = N+alpha+2/N with alpha is an element of (0, N) for N >= 2 is the mass critical exponent. Here I-alpha denotes the Riesz potential and the trapping potential 0 <= V(x) is an element of L-loc(infinity)(R-N) satisfies lim(vertical bar x vertical bar ->infinity) V(x) = infinity . We prove that minimizers exist if and only if a satisfies a < a* = parallel to Q parallel to(2(p-1))(2) , where Q is a positive radially symmetric ground state of -Delta u + u = (I-alpha *vertical bar u vertical bar(p))vertical bar u vertical bar(p-2)u in R-N. The uniqueness of positive minimizers holds if a > 0 is small enough. The blow-up behavior of positive minimizers as a NE arrow a* is also derived under some general potentials. Especially, we prove that minimizers must blow up at the central point of the biggest inscribed sphere of the set Omega := {x is an element of R-N, V(x) = 0} if vertical bar Omega vertical bar > 0.
