Some examples due to H. Hironaka
Abstract
The aim of this paper is to explain the construction by H. Hironaka [H.61] of a holomorphic (in fact "algebraic") family of compact complex manifolds parametrized by such for all s ∈ \0\ the fiber is projective, but such that the fiber at the origin in non k\"ahlerian, to mathematicians which are not algebraic geometers. We also explain why it is not possible to make in the same way such an example with fiber at 0 a simpler example of non k\"ahlerian Moishezon manifold which is also due to H. Hironaka (see section 5).
