李群胚的整体二分性

On the Existence of Global Bisections of Lie Groupoids

Z. Chen, Z. -J. Liu, D. -S. Zhong

摘要:

证明了每个源连通李群胚都有通过任意给定点的整体对分。这个二等分可以被选择为尽可能接近指定曲线的一些指数的乘法。还讨论了通过多个指定点的二分法的存在性。我们给出了这些结果的一些有趣的应用。

英文摘要:

We show that every source connected Lie groupoid always has global bisections through any given point. This bisection can be chosen to be the multiplication of some exponentials as close as possible to a prescribed curve. The existence of bisections through more than one prescribed points is also discussed. We give some interesting applications of these results.
