Abstract
We study the following nonlinear Hartree-type equation
where \(a>0\), \(N\ge 3\), \(\gamma \in (1,2)\) and V(x) is an external potential. We first study the asymptotic behavior of the ground state of equation for \(V(x)\equiv 1\), \(a=1\) and \(\lambda =0\) as \(\gamma \nearrow 2\). Then, we consider the case of some trapping potential V(x) and show that all the mass of ground states concentrate at a global minimum point of V(x) as \(\gamma \nearrow 2\), which leads to symmetry breaking. Moreover, the concentration rate for maximum points of ground states will be given.
