摘要
将三维殴氏空间中的纽结L在平面上的投影图转换成边带有±1号的平图G(L)。G(L)之间的同构、自对偶性可以分别来描述L的同痕性、手征性。利用将纽结转换成平图的方法,能方便地设计出复杂的纽结图案。
There are many sorted topological invariants in knot theory , which can be used to differentiate different inequivalent knots . This paper, the plane projective graph of knot Lin 3-space was transformed into plane graph of edges with '±1' symbol , the eguivalence and mirrorimage characters of knot L were described by the isomorph and the selfdual quality of G(L).
