考虑下面的带位势耦合薜定谔方程组,
其中 N=1,2,3,Vi(x)和Qij(x)(1≤i,j≤2)是正的连续函数且满足Q12(x)=Q21(x).我们利用Nehari流形和Ekeland变分原理证明了一个半正基本态解的存在及其性质.

To study the Schrödinger equations with potentials:
where N=1,2,3,Vi(x)with Qij(x)(1≤i,j≤2)are positive continuous functions satis fying Q12(x)=Q21(x).We use the Nehari manifold and Ekeland′s variational principle to proof the existing of a semi-positive ground state and it′s property.
