A variation of McShane’s identity for 2–bridge links
A variation of McShane’s identity for 2–bridge links
We give a variation of McShane's identity, which describes the cusp shape of a hyperbolic 2-bridge link in terms of the complex translation lengths of simple loops on the bridge sphere.We also explicitly determine the set of end invariants of SL.2; C/-characters of the once-punctured torus corresponding to the holonomy …
