On the Arf invariant of links
Published online by Cambridge University Press: 24 October 2008
Extract
In ([2], p. 310) the problem of relating the Arf invariant of a link to other link invariants, and finding practical ways of computing it, was raised. Murasugi gave a partial solution to this in [9]: if L has two components, then Arf(L), when defined, is given by
where l1, l2 are the components of L, and ΔL(t1, t2) denotes the Alexander polynomial of L.
