摘要：In this talk we will discuss some recent results on compact
Kahler manifolds with nonnegative quadratic orthogonal bisectional
curvature. Some elementary properties on the structure of such class of manifolds will be given. Motivated by the result and conjectures  of Li-Wu-Zheng, we will give necessary and sufficient conditions for an irreducible Kahler  $C$-space of classical type to have nonnegative or positive  quadratic bisectional curvature, assuming the space is not Hermitian symmetric.
