论文摘要
结在低维拓扑中起着至关重要的作用。我们提出了一种非常基本的技术，该技术使人们可以为整个圆环中的结构构成许多切片障碍。我们的方法涉及小组理论技术；它是完全组合的，小组非常容易处理。
Knot concordance plays a crucial role in the low dimensional topology. We propose a very elementary techniques which allows one to construct a lot of sliceness obstructions for knots in the full torus. Our approach deals with group theoretical techniques; it is completely combinatorial, and the groups are very easy to deal with.
