“…, n; when M 2 is a sphere one needs n ≥ 3. There exists on M 2 \ {p k } n k=1 a smooth function ω, with puncture singularities, or cusps, at the points p k , such that the metric e ω h is complete, has constant Gauss curvature equal to −1, and such that M 2 , e ω h has finite total area; compare [8, Proposition 2.3], [17], and references therein. An artist's impression of a punctured torus can be seen in Figure 2.…”
