In this paper, we consider the following Schrödinger equations with critical growthâÎu+(λa(x)âδ)u=|u|2ââ2u,xâRN, where Nâ¥4, 2â is the critical Sobolev exponent, a(x)â¥0 and its zero sets are not empty, λ>0 is a parameter, δ>0 is a constant such that the operator (âÎ+λa(x)âδ) might be indefinite for λ large. We prove that if the zero sets of a(x) have several isolated connected components Ω1,â¯,Ωk such that the interior of Ωi(i=1,2,â¦,k) is not empty and âΩi(i=1,2,â¦,k) is smooth. Then for λ sufficiently large, the equation admits, for any iâ{1,2,â¯,k}, a solution which is trapped in a neighborhood of Ωi. The key ingredients of the paper are using a flow argument and a combination of global linking and local linking.
