论文摘要
$υ$不变性是通过使用打结浮子同源性定义的一致性不变性。 Földvári使用网格同源性对IT进行了组合重组。我们使用平衡空间图扩展了平衡空间图的组合$υ$不变。关于作为空间图的链接，当两个链接通过COBORDISM连接时，我们给出了$υ$的上限和下限。我们还表明，组合$υ$是结的一致性。
The $Υ$ invariant is a concordance invariant defined by using knot Floer homology. Földvári gives a combinatorial restructure of it using grid homology. We extend the combinatorial $Υ$ invariant for balanced spatial graph using grid homology for balanced spatial graph. Regarding links as spatial graphs, we give a upper and lower bounds for $Υ$ when two links are connected by a cobordism. Also we show that the combinatorial $Υ$ is a concordance invariant for knots.
