Do products of locally conformally K\"ahler manifolds (LCK, for short) carry an LCK metric?

Abstract:
An LCK (locally conformally Kähler) manifold is a Hermitian manifold
which admits a Galois cover which has a Kähler metric such that the
deck group is acting by holomorphic homotheties. The product of two LCK manifolds
does not have a natural product LCK structure. It is believed that a product of two
compact complex manifolds is never LCK.
We classify all known examples of compact LCK manifolds in two classes:
manifolds containing a curve and manifolds of Inoue type.
In the talk we will outline the description of these classes and the
proof that a product of a compact complex manifold and an LCK manifold
belonging to one of these classes above does not admit an LCK structure.
The talk is based on joined work with L. Ornea and M. Verbitsky.
