Abstract

Let MM be a real hypersurface of a complex space form with constant curvature cc. In this paper, we study the hypersurface MM admitting Miao-Tam critical metric, i.e. the induced metric gg on MM satisfies the equation:(Δgλ)g+g2λλRic=g-(\Delta_g\lambda)g+\nabla^2_g\lambda-\lambda Ric=g, where λ\lambda is a smooth function on MM. At first, for the case where MM is Hopf, c=0c=0 and c0c\neq0 are considered respectively. For the non-Hopf case, we prove that the ruled real hypersurfaces of non-flat complex space forms do not admit Miao-Tam critical metrics. Finally, it is proved that a compact hypersurface of a complex Euclidean space admitting Miao-Tam critical metric with λ>0\lambda>0 or λ<0\lambda<0 is a sphere and a compact hypersurface of a non-flat complex space form does not exist such a critical metric.
