A short note on the Love number of extremal Reissner-Nordstrøm and Kerr-Newman black holes

We provide a simple proof of why the Love number vanishes for extremal Reissner-Nordstrøm and Kerr-Newman black holes. The argument is based on a conformal inversion isometry of the spacetime connecting the horizon with large distances.
