Seifert surgery on knots via Reidemeister torsion and Casson-Walker-Lescop invariant III

Teruhisa Kadokami, Noriko Maruyama, Tsuyoshi Sakai

For a knot $K$ in a homology $3$-sphere $\Sigma$, let $M$ be the result of $2/q$-surgery on $K$, and let $X$ be the universal abelian covering of $M$. Our first theorem is that if the f…
