摘要: This paper is concerned with existence of bound states for Schrodinger systems which have appeared as several models from mathematical physics. We establish multiplicity results both small and large interactions. done by different approaches depending upon the sizes interaction parameters in systems. For interactions we give a new approach to deal multiple states. The novelty our lies establishing certain type invariant sets associated gradient flows. use minimax procedure distinguish solutions analyzing their Morse indices.
