论文摘要
让$ k $是一个完美的领域,而$ x $是$ k $以上的平滑投影曲线。我们给出了$ x $的矢量捆绑包的标准,以承认有限的$ x $的对数连接单数,并带有给定的残留物,其中残留物被认为是刚性的。
Let $k$ be a perfect field, and $X$ an irreducible smooth projective curve over $k$. We give a criterion for a vector bundle over $X$ to admit a logarithmic connection singular over a finite subset of $X$ with given residues, where residues are assumed to be rigid.
