On strongly Gauduchon metrics of compact complex manifolds

In this paper, we study strongly Gauduchon metrics on compact complex manifolds. We study the cohomology cones SG in the de Rham cohomology groups generated by all strongly Gauduchon metrics and its direct images under proper modifications. We also study the moduli of strongly Gauduchon manifolds. We prove an existence result of strongly Gauduchon metrics on compact complex manifold which is fibred over a compact complex curve. In particular, if a compact complex manifold X has a topologically essential fibration over a compact complex curve, and if the generic fibres satisfy ddbar-lemma, then X admits strongly Gauduchon metrics.
