Abstract. We consider the existence multiple solutions to the linearly
coupled elliptic system
in
in
in
on
where is a bounded domain with smooth boundary in , , are constants, is the first eigenvalue of , is a coupling parameter, are nonnegative, and is the upper critical exponent in the sense of the Hardy-Littlewood-Sobolev inequality. We prove that the system has a positive ground state solution by mountain pass theorem for small . By a perturbation argument, when , comparing with the mountain pass type solution, another positive higher energy solution is obtained when is small. In addition, the asymptotic behaviours of these solutions are analyzed as $\beta\rightarrow0$.
