In recent papers Wu-Yau, Tosatti-Yang and Diverio-Trapani, used some natural differential inequalities for compact Kähler manifolds with quasi negative holomorphic sectional curvature to derive positivity of the canonical bundle. In this note we study the equality case of these inequalities.

Wu-Yau不等式中的等式案例

在最近的论文中，Wu-Yau，Tosatti-Yang和Diverio-Trapani对准负全同形截面曲率的紧Kähler流形使用了一些自然微分不等式来推导正则束的正性。在本文中，我们研究了这些不平等的平等情况。
