Biography：Professor Wenhao Ou obtained his PhD degree from Grenoble Alps University, France,then he was Postdoctoral Fellow at University of Bonn and UCLA, now is an associate professor at Chinese Academy of Science working on algebraic geometry. Professor Ou made fundamental contributions to studying the Kahler varieties: including Kähler abundance in low dimension, Orbifold modifications of complex analytic varieties, and characterization of uniruled compact Kähler manifolds.
Title：A characterization of uniruled Kaehler manifolds
Abstract: We adapt Bost's algebraicity characterization to the situation of a germ in a compact Kaehler manifold.
As a consequence, we extend the algebraic integrability criteria of Campana-Paun and of Druel to foliations on compact Kaehler manifolds.
As an application, we prove that a compact Kaehler manifold is uniruled if and only if its canonical line bundle is not pseudoeffective.
