摘要
本文讨论了几乎交错纽结补中的不压缩,两两不可压缩曲面的性质.证明了,当K是素的几乎交错纽结时,若FS3-K是不可压缩、两两不可压缩曲面,则对于固定的边界分支数n,曲面F的合痕类是有限的.
In this paper, we deal with incompressible, pairwise incompressible surface in almost altemating knot complements Let K be a prime almost alternating knot We proved that for fixed n, there are only finitely many iucompressible , pairwise incompressible surfaces F with n boundary components and with F S3-K up to isotopy.
