摘要
Under the assumption that F is asymptotically or super linear as |U| -> a with U = (u, v) a a"e(2), we obtain the existence of ground state solutions of a class of cooperative elliptic systems in a"e (N) by using a variant generalized weak linking theorem for strongly indefinite problem developed by Schechter and Zou. To the best of our knowledge, there is no result published concerning the systems in the whole space R-N.
