摘要
A locally conformally Ka.hler (LCK) manifold is a complex manifold M which has a Ka.hler structure on its cover, such that the deck transform group acts on it by homotheties. Assume that the Ka.hler form is exact on the minimal Ka.hler cover of M. We prove that any bimeromorphic map M' -> M is in fact holomorphic; in other words, M has a unique minimal model. This can be applied to a wide class of LCK manifolds, such as the Hopf manifolds, their complex submanifolds and to OT manifolds.
