考慮下面的帶位勢(shì)耦合薜定諤方程組,
其中 N=1,2,3,Vi(x)和Qij(x)(1≤i,j≤2)是正的連續(xù)函數(shù)且滿足Q12(x)=Q21(x).我們利用Nehari流形和Ekeland變分原理證明了一個(gè)半正基本態(tài)解的存在及其性質(zhì).

To study the Schr?dinger 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.
