一类重要的三流形是L-空间,它是具有最小可能的弗洛尔同调的有理同调球面。对于具有瞬子L-空间手术的结,我们计算所有积分手术的框架瞬子Floer同调。因此,如果一个结有一个Heegaard Floer和instanton Floer L空间手术,那么所有的积分手术理论都是一致的。为了证明主要结果,我们证明了框架瞬子Floer同调中的Baldwin-Sivek接触不变量关于绝对$\mathbb{Z}/2$-分次是齐次的,但关于绝对$\mathbb{Z}/4$-分次不是齐次的.
An important class of three-manifolds are L-spaces, which are rational homology spheres with the smallest possible Floer homology. For knots with an instanton L-space surgery, we compute the framed instanton Floer homology of all integral surgeries. As a consequence, if a knot has a Heegaard Floer and instanton Floer L-space surgery, then the theories agree for all integral surgeries. In order to prove the main result, we prove that the Baldwin-Sivek contact invariant in framed instanton Floer homology is homogeneous with respect to the absolute $\mathbb{Z}/2$-grading, but not the $\mathbb{Z}/4$-grading.
