Let Θ(M,K) denote the 2-loop piece of (the logarithm of) the LMO invariant of a knot K in M , a ZHS . Forgetting the knot (by which we mean setting diagrams with legs to zero) specialises Θ(M,K) to λ(M), Casson’s invariant. This note describes an extension of Casson’s surgery formula for his invariant to Θ(M,K). To be precise, we describe the effect on Θ(M,K) of a surgery on a knot which together with K forms a boundary link in M . Whilst the presented formula does not characterise Θ(M,K), it… Expand
On the 2-loop polynomial of knots
The 2‐loop polynomial of a knot is a polynomial characterizing the 2‐loop part of the Kontsevich invariant of the knot. An aim of this paper is to give a methodology to calculate the 2‐loopExpand
Surgery on a single clasper and the 2-loop part of the Kontsevich integral
We study the 2-loop part of the rational Kontsevich integral of a knot in an integer homology sphere. We give a general formula which explains how the 2-loop part of the Kontsevich integral of a knotExpand

Morita's trace maps on the group of homology cobordisms
Morita introduced in 2008 a 1-cocycle on the group of homology cobordisms of surfaces with values in an infinite-dimensional vector space. His 1-cocycle contains all the "traces" of JohnsonExpand
A Cabling Formula for the 2-Loop Polynomial of Knots
The 2-loop polynomial is a polynomial presenting the 2-loop part of the logarithm of the Kontsevich invariant of knots. We show a cabling formula for the 2-loop polynomial of knots. In particular, weExpand
Perturbative invariants of 3–manifolds with the first Betti number 1
It is known that perturbative invariants of rational homology 3‐spheres can be constructed by using arithmetic perturbative expansion of quantum invariants of them. However, we could not makeExpand

The loop expansion of the Kontsevich integral, the null-move and S-equivalence ☆
Abstract The Kontsevich integral of a knot is a graph-valued invariant which (when graded by the Vassiliev degree of graphs) is characterized by a universal property; namely it is a universalExpand
The loop expansion of the Kontsevich integral, abelian invariants of knots and S-equivalence
Hidden in the expansion of the Kontsevich integral, graded by loops rather than by degree, is a new notion of finite type invariants of knots, closely related to S-equivalence, and with respect toExpand
