Locally Conformally Kähler Manifolds of Algebraic Codimension One

Abstract

A locally conformally Kähler (LCK) manifold is a manifold $M$ which admits a Kähler structure on its universal cover $\tilde{M}$, in such a way that the monodromy acts conformally on $\tilde{M}$. Let $M$ be an $n$-dimensional compact LCK manifold of algebraic dimension $n-1$. We prove that $M$ is bimeromorphic to the total space of an isotrivial elliptic fibration. Morever, there exists an alteration of $M$ which dominates bimeromorphically a manifold admitting a free action of an elliptic curve.
