“…The appearance of the nonlocal term in the equations not only makes it important in many physical applications but also causes some difficulties and challenges from a mathematical point of view. Therefore, in the past several decades, there has been an increasing attention toward systems (1.2) or similar problems, and the existence of positive, multiple, bound state, multi-bump, as well as semiclassical state solutions has been investigated; see, for example, [4,7,9,10,13,16,21,24,29,37,38,43,[47][48][49]60]. Besides, He and Zou [23] considered multiplicity of concentrating positive solutions for a class of double parameter perturbed Schrödinger-Poisson equation with critical growth.…”
