关于陈微分式的一个注记(英文)

A Remark on Chern Form In memory of Professor Wu Guanglei on His 80th Anniversary

在陈省身先生关于高斯-波涅公式的著名证明中有一个关键等式,本文对这一等式给出一个稍稍改动的证明,相信更清楚地贴近陈的想法。

In the famous Chern's proof for the Gauss-Bonnet formula, there is a key identity. Now we show a little improved proof for that identity. We believe that it is closer to Chern's ideas.
