The metric ds = |dz|/(1 + |z|^2) has constant positive Gauss curvature equal to 4 and extends to the complex plane plus the point at infinity. How does this metric relate to the usual metric of constant Gauss curvature computed from the unit sphere in Euclidean 3 space?(adsbygoogle = window.adsbygoogle || []).push({});
