吴鹏最近利用Det(W^+)>0条件,给出了紧致定向4-流形上正数量曲率的共形Kaehler,Einstein度量的一个美丽刻画。在这个笔记中,我们通过对他的结果提供完全不同的证据来支持他的说法。然后,我们介绍了我们的方法的进一步结果,该方法建立在先前在(LeBrun 2015)中开发的技术的基础上。
Peng Wu recently announced a beautiful characterization of conformally Kaehler, Einstein metrics of positive scalar curvature on compact oriented 4-manifolds via the condition det (W^+) > 0. In this note, we buttress his claim by providing an entirely different proof of his result. We then present further consequences of our method, which builds on techniques previously developed in (LeBrun 2015).
