Abstract
This paper is concerned with the following elliptic system:
Assuming that the potential U i (x) are periodic in x and 0 lies in a spectral gap of \({\sigma (-\Delta + U_{i}), i=1,2}\), two types of ground state solutions are obtained with some new super-quadratic conditions on nonlinearity F which are weaker that some well known ones. For the case that U i (x) and F(x,u,v) are asymptotically periodic in x, a nontrivial solution is established by using a generalized linking theorem and some new techniques.
