本文研究了Nori基本群的同伦序列为正合的充要条件，并将其应用于各种特殊情形，得到了一些经典定理，同时给出了一个反例，说明这些条件并不总是满足的.这一工作部分是基于H. Esnault，P.- H. Hai，E.维韦格
In this paper, we investigate the necessary and sufficient conditions for the exactness of the homotopy sequence of Noriʼs fundamental group and apply these to various special situations to regain some classical theorems and give a counterexample to show the conditions are not always satisfied. This work is partially based on the earlier work of H. Esnault, P.-H. Hai, E. Viehweg.
