A rho-invariant of iterated torus knots

Abstract

We compute rho-invariant for iterated torus knots KK for the standard representation of the knot group given by abelianisation. For algebraic knots, this invariant turns out to be very closely related to an invariant of a plane curve singularity, coming from algebraic geometry.

Comments

Corrected the left hand side of equations (4.2) and (4.3). The statement in Proposition 4.6 is also corected. The expression for H^2 on the bottom of page 10 has now correct sign
