本文证明了三维流形的扭Blanchfield对的一个分解公式。作为一个应用,我们表明,扭曲的Blanchfield配对的3-流形从一个3-流形Y表示$\phi:Z[\pi_1(Y)] \到R$,被结J沿着具有$\phi(\eta)\neq 1$的曲线$\eta$感染,正交分裂为Y的扭曲Blanchfield配对和结J的普通Blanchfield配对的和,其中后者从$Z[t,t^{-1}]$张量到R。
We prove a decomposition formula for twisted Blanchfield pairings of 3-manifolds. As an application we show that the twisted Blanchfield pairing of a 3-manifold obtained from a 3-manifold Y with a representation $\phi: Z[\pi_1(Y)] \to R$, infected by a knot J along a curve $\eta$ with $\phi(\eta) \neq 1$, splits orthogonally as the sum of the twisted Blanchfield pairing of Y and the ordinary Blanchfield pairing of the knot J, with the latter tensored up from $Z[t,t^{-1}]$ to R.
