Let L be an alternating link in S~3 and let L project on S~2 except near crossings of L where L lies on a bubble.
设L是S3中的一个交错环链,将L投影到S2上,L的每个交叉点都对应一个bubble,用来体现L的交叉点性质。
Let L be an alternating link in S3 and Let Lproject on S2 except near crossings of L where L lies on a bubble.
本文讨论了交错环链补中的不可压缩、分段不可压缩曲面的性质。
