3D plots over the Riemann sphere Real part (left) and imaginary part (right) of over the Riemann sphere. The inward‐outward bending of a unit sphere is proportional to and . The essential singularity at results in a complicated structure at the north pole. The quarter‐space is not shown. Values of as a Riemann sphere vectorially added to the Riemann sphere of . Shown is the part .
