我们构造了一个积分同调球,其值在多项式环的补全中,使得在单位ζ的每一个根处的求值给出了matζ的u (2) wittten - reshetikhin - turaev不变量τζ(M)。因此统一了m的所有u (2) Witten-Reshetikhin-Turaev不变量。也可以得出τζ(M)作为ζ上的函数,其行为类似于定义在一组统一根上的“解析函数”。
We construct an invariantJMof integral homology spheresMwith values in a completionof the polynomial ring ℤ[q] such that the evaluation at each root of unity ζ gives the theSU(2) Witten–Reshetikhin–Turaev invariant τζ(M) ofMat ζ. ThusJMunifies all theSU(2) Witten–Reshetikhin–Turaev invariants ofM. It also follows that τζ(M) as a function on ζ behaves like an “analytic function” defined on the set of roots of unity.
