本文利用Khovanov同调的Lee和Bar-Natan变形构造了一个非定向曲面的混合不变量,并用它来区分由同一结点限定的曲面对,包括一些奇异的例子。参考文献
We construct a mixed invariant of nonorientable surfaces from the Lee and Bar-Natan deformations of Khovanov homology and use it to distinguish pairs of surfaces bounded by the same knot, including some exotic examples. References
