Hans U. Boden, Christopher M. Herald
TL;DR
This paper calculates the $SU(2)$ Casson-Lin invariant for the Hopf link and clarifies the sign in the relation between this invariant and the linking number.
Contribution
It provides the explicit computation of the invariant for the Hopf link and resolves the sign ambiguity in the existing formula.
Findings
Computed the $SU(2)$ Casson-Lin invariant for the Hopf link.
Determined the correct sign in the relation to linking number.
Clarified the connection between the invariant and classical linking number.
Abstract
We compute the Casson-Lin invariant for the Hopf link and determine the sign in the formula of Harper and Saveliev relating this invariant to the linking number.
