We analyze a special spectral transform of a measure supported on a compact subset C of the complex plane. A perturbation 1 of is said to be a Geronimus spectral transform if d 1 = d |z -| 2 where / ∈ C. We focus our attention in the analysis of the Hessenberg matrix associated with the multiplicati
