Locally Conformally Kähler Manifolds of Algebraic Codimension One

Liviu Ornea, Misha Verbitsky, Victor Vuletescu

A locally conformally Kähler (LCK) manifold is a manifold which admits a Kähler structure on its universal cover , in such a way that the monodromy acts conformally…

Dolbeault cohomology of Endo-Pajitnov manifolds

Liviu Ornea, Miron Stanciu

Endo-Pajitnov manifolds are compact non-Kähler manifolds which generalize the Inoue surfaces to higher dimensions. We compute their Dolbeault cohomology and show that they s…

Conformal foliations, Kähler twists and the Weinstein construction

Paul-Andi Nagy, Liviu Ornea

We classify both local and global Kähler structures admitting totally geodesic homothetic foliations with complex leaves. The main building blocks are related to Swann's twists an…

Special non-Kähler metrics -- old and new

Liviu Ornea, Miron Stanciu

We give an account of old and new results concerning many types of non-Kähler metrics, with focus on the problem of their coexistence on compact complex manifolds, and their behav…

Principles of Locally Conformally Kahler Geometry

Liviu Ornea, Misha Verbitsky

An LCK (locally conformally Kahler) manifold is a complex manifold admitting a Kahler covering with monodromy acting by homotheties. Hopf manifolds and their submanifolds are the p…

The Lee--Gauduchon cone on complex manifolds

Liviu Ornea, Misha Verbitsky

Let be a compact complex -manifold. A Gauduchon metric is a Hermitian metric whose fundamental 2-form satisfies the equation . Paul Gauduchon has prov…
