摘要：In this talk，we study a nonlinear equation with a fractional Laplacian operator and almost critical exponents. Under some suitable assumptions of the potential function, we will use the finite dimensional reduction method and some local Pohozaev identities to prove that this problem has large number of bubble solutions. The concentration points of the bubble solutions include a saddle point of the potential function. We also give the concentrating rates of the bubble solutions. This is based on a joint work with S. T. Wei.
