本文在有边三元流形的有边缝合Heegaard Floer同调中引入了一个切触不变量。不变量的输入是一个接触流形,其凸边界配备了一个密切相关的特征叶理的签署奇异叶理。这样一个流形允许一族由Giroux对应分类的叶状开书分解,如[LV 20]所述。我们使用一类特殊的叶状开书构造容许边界缝合Heegaard图,并确定定义良好的类和相应的边界缝合模块。 叶状开放书籍表现出用户友好的胶合行为,我们表明,胶合兼容叶状开放书籍引起的不变量配对恢复Heegaard Floer接触不变量封闭接触流形。我们还考虑了一个自然映射,忘记了叶理有利于分割集,并表明它映射的边界缝合不变量的缝合流形的接触不变量的Honda-Kazez-Matić定义。
We introduce a contact invariant in the bordered sutured Heegaard Floer homology of a three-manifold with boundary. The input for the invariant is a contact manifold whose convex boundary is equipped with a signed singular foliation closely related to the characteristic foliation. Such a manifold admits a family of foliated open book decompositions classified by a Giroux correspondence, as described in [LV20]. We use a special class of foliated open books to construct admissible bordered sutured Heegaard diagrams and identify well-defined classes and in the corresponding bordered sutured modules. Foliated open books exhibit user-friendly gluing behavior, and we show that the pairing on invariants induced by gluing compatible foliated open books recovers the Heegaard Floer contact invariant for closed contact manifolds. We also consider a natural map associated to forgetting the foliation in favor of the dividing set and show that it maps the bordered sutured invariant to the contact invariant of a sutured manifold defined by Honda–Kazez–Matić.
