摘要

We study a Schr(o)dinger system with the sum of linear and nonlinear couplings.Applying index theory,we obtain infinitely many solutions for the system with periodic potentials.Moreover,by using the concentration compactness method,we prove the existence and nonexistence of ground state solutions for the system with close-to-periodic potentials.
