Abstract:

We prove that a compact locally conformai Kähler manifold which satisfies either: (1) it has nonpositive conformal invariant $\mu$ [2] and its local conformal Kähler metrics have nonnegative scalar curvature or (2) its local conformal Kähler (l.c.K.) metrics have a positive or negative definite Ricci form is a Kahler manifold. We conjecture that every compact l.c.K. manifold which satisfies all the topological restrictions of a Kähler manifold admits some Kähler metric.
