Let X be a connected smooth complex projective variety of dimension $$n \ge 1$$ n ≥ 1 . Let D be a simple normal crossing divisor on X . Let G be a connected complex Lie group, and $$E_G$$ E G a holomorphic principal G -bundle on X . In this article, we give criterion for existence of a logarithmic connection on $$E_G$$ E G singular along D .

光滑复射影变数上主丛存在对数联系的判据

设 X 是维数 $$n \ge 1$$ n ≥ 1 的连通光滑复射影变体。令 D 是 X 上的一个简单的正态交叉除数。设 G 是一个连通复李群,而 $$E_G$$ EG 是 X 上的全纯主 G -bundle。在本文中,我们给出了沿 D 的 $$E_G$$ EG 奇异对数连接存在的标准。
