Abstract:

We compute the Reidemeister-Turaev torsion of homology cylinders which takes values in the $K_1$-group of the $I$-adic completion of the group ring $\mathbb {Q}\pi _1\Sigma _{g,1}$, and prove that its reduction to $\widehat {\mathbb {Q}\pi _1\Sigma _{g,1}}/\hat {I}^{d+1}$ is a finite-type invariant of degree $d$. We also show that the $1$-loop part of the LMO homomorphism and the Enomoto-Satoh trace can be recovered from the leading term of our torsion.
