| 中文摘要: |
| 研究了在曲面拓扑图的每个球泡中最多有一个鞍点的情况下,拓扑图的简单性与曲面亏格的关系. 并利用正方形素方割的性质讨论了素、非分离几乎交错链环补空间中的闭、不可压缩、分段不可压缩曲 面的性质. |
| 英文摘要: |
| The authors discuss the relationship between the simplicity of the topological graph and the genus of the surface when there is at most one saddle in each bubble of the surface’s topological graph. And the properties of closed, incompressible and pairwise incompressible surfaces in prime, almost alternating link complements are discussed by using the properties of the prime dissection of a square. |
