设Em表示区间I = [?1,1]中的立方体Im的端点和切向量在这些端点固定在立方体的相对面,配备了一个同伦通过浸入unknot;见定义5.1。根据命题5.17,Em同伦等价于Emb(I,Im)xi?lmm(l,Im)。在[28]中,麦克卢尔和史密斯定义了一个余单对象O*,它与一个乘法为0的操作数相关联,我们将其同伦不变量积记为Tot(?#);见下文定义2.17和定义2.5。令/Cm表示在[22]中引入的拉特Kontsevich操作,其条目是紧化的配置空间,并且弱等价于小ra-圆盘操作[37];参见定义4.1和定理4.5。
Let Em denote the space of embeddings of the interval I = [?1,1] in the cube Im with endpoints and tangent vectors at those endpoints fixed on opposite faces of the cube, equipped with a homotopy through immersions to the unknot; see Definition 5.1. By Proposition 5.17, Em is homotopy equivalent to Emb(I,Im) x i?lmm(l, Im). In [28], McClure and Smith define a cosimplicial object O* associated to an operad with multiplication 0, whose homotopy invariant totalization we denote Tot(?#); see Definition 2.17 and Definition 2.5 below. Let /Cm denote the rath Kontsevich operad, introduced in [22], whose entries are compactified configuration spaces and which is weakly equivalent to the little ra-disks operad [37]; see Definition 4.1 and Theorem 4.5.
