本文扩展Khovanov-Lee同调至特定三维流形中的链环,构造Rasmussen型不变量,并证明其与四维流形中曲面亏格的不等式关系。
AI 中文摘要
我们将Khovanov-Lee同调的定义推广到曲面上的区间丛的连通和以及$S^1\times S^2$中的链环,并为这些流形中的链环构造了一个Rasmussen型不变量。作为应用,我们证明了一个不等式,将Rasmussen型不变量与四维流形中带边曲面的亏格联系起来,这些四维流形是$D^2\times S^2$、$\mathbb{C} P^2\setminus B^4$和$DTS^2$的边界连通和。
英文摘要
We extend the definition of Khovanov-Lee homology to links in connected sums of interval bundles over surfaces and $S^1\times S^2$'s, and construct a Rasmussen-type invariant for links in these manifolds. As an application, we prove an inequality relating the Rasmussen-type invariant to the genus of surfaces with boundary in four-manifolds that are boundary connect sums of $D^2\times S^2$, $\mathbb{C} P^2\setminus B^4$, and $DTS^2$.
