本文研究非齐次Hartree方程的Cauchy问题:iut=−Δu−k(x)<$RNk(y)|x−y| 2| u(t,y)|2dyu(t,x),x∈RN,N ∈ 3.首先,我们建立了爆破解的质量集中性质。其次,我们证明了具有最小质量的爆破解应该集中在临界点k处。最后,在对k的全局最大值点的某些假设下,我们建立了这样的解的不存在性。
In this paper, we are concerned with the Cauchy problem of the inhomogeneous Hartree equation: iut=−Δu−k(x)∫RNk(y)|x−y|2|u(t,y)|2dyu(t,x), x∈RN, N ⩾ 3. First, we establish the mass concentration property of the blow-up solutions. Second, we show that the blow-up solutions with minimal mass should concentrate at a critical point of k. Finally, under certain assumptions on global maximum points of k we establish nonexistence of such solutions.
