论文摘要
在本文中，我们考虑了星形图$ s_n $带有$ n $ vertices的所有部分异构体的单差$ dps_n $。我们的主要目标是确定排名并展示$ dps_n $的演示文稿。我们还描述了格林的$ dps_n $的关系并计算其红衣主教。
In this paper we consider the monoid $DPS_n$ of all partial isometries of a star graph $S_n$ with $n$ vertices. Our main objectives are to determine the rank and to exhibit a presentation of $DPS_n$. We also describe Green's relations of $DPS_n$ and calculate its cardinal.
