论文摘要
Stukow给出了所有Dehn Twists产生的紧凑型非定向表面的映射类别组的有限陈述。在本文中，我们为该组提供了无限的介绍，主要使用Stukow和Birman精确序列在映射不可取向表面的类组上给出的介绍。
A finite presentation for the subgroup of the mapping class group of a compact non-orientable surface generated by all Dehn twists was given by Stukow. In this paper, we give an infinite presentation for this group, mainly using the presentation given by Stukow and Birman exact sequences on mapping class groups of non-orientable surfaces.
