Bimeromorphic geometry of LCK manifolds
Published 7 Feb 2023 in math.DG, math.AG, and math.CV | (2302.03422v1)
Abstract: A locally conformally K\"ahler (LCK) manifold is a complex manifold $M$ which has a K\"ahler structure on its cover, such that the deck transform group acts on it by homotheties. Assume that the K\"ahler form is exact on the minimal K\"ahler cover of $M$. We prove that any bimeromorphic map $M'\rightarrow M$ 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.
