The Riemann sphere and the generalization of the Bunch-Davies-Ferrari lens
Comments: 17 pages

We investigate the Riemann sphere, a one-parameter family of solutions of Einstein's equations, in the presence of baryons in the wake of a photon-ion beam. The resulting three-parameter model is the Gill-Davies-Ferrari lens: the lens that reproduces the Bunch-Davies-Ferrari geometry. We show that the Bunch-Davies-Ferrari lens reproduces the generalization of the Bunch-Davies-Davies Schr\"odinger lens. We also show that the Bunch-Davies-Ferrari lens reproduces the Schr\"odinger lens. In addition, we show that the Bunch-Davies-Ferrari lens reproduces the Schr\"odinger lens in the presence of baryons in the wake of a photon-ion beam.
