Abstract

We revisit Brunella's proof of the fact that Kato surfaces admit locally conformally K\" ahler metrics, and we show that it holds for a large class of higher dimensional complex manifolds containing a global spherical shell. On the other hand, we construct manifolds containing a global spherical shell which admit no locally conformally K\"ahler metric. We consider a specific class of these manifolds, which can be seen as a higher dimensional analogue of Inoue-Hirzebruch surfaces, and study several of their analytical properties. In particular, we give new examples, in any complex dimension n3n \geq 3, of compact non-exact locally conformally K\" ahler manifolds with algebraic dimension n2n-2, algebraic reduction bimeromorphic to CPn2\mathbb{C}\mathbb{P}^{n-2} and admitting non-trivial holomorhic vector fields.
