  1. We obtain a relation between the Nielsen number of coincidence points of two Dehn twists and the minimal geometric intersection number of the simple closed curves determining these two Dehn twist .

    本文中,我们主要讨论曲面上一种特殊自同胚&Dehntwist的重合点,给出了重合点Nielsen数与闭曲线的最小几何相交数的联系。

  2. In this thesis , our main aim is to estimate the minimal geometrical intersection number of two degenerating slope on hyperbolic 3-manifold , this is also one of the hotspots in the 3-manifold theory .

    在本文中,我们将引用几何相交数的概念来估测双曲流形上退化的把柄添加的个数,这也是三维流形理论中比较热点的话题之一。

  3. In terms of neighborhood intersection with independent number , a new degree sum condition about minimum degree for a graph to be hamiltonian is given in this paper . It is shown that 3-connected graphs G under this condition are Hamilton-connected .

    结合关于独立数的邻域交条件,给出了图G为Hamilton图的关于最小度的新度和条件,并且证明了在此种条件下3连通图G是Hamilton连通的。
