Does there exist a regular simple closed curve on a compact surface which cuts the surface into two regions, each with total Gaussian curvature of ? Select one: O a. Yes, and an example is given by a circle on a torus of revolution obtained by rotating this circle about an axis. b. Yes, and an example is given by the equator on the unit sphere. О с. Yes, and an example is given by the unit circle defined by z = 0 on the hyperboloid of one sheet x² + y² = z² = 1. No, by the Jordan curve theorem. No, by Hopf's Umlaufsatz. O f. No, by Fenchel's theorem. Og. No, by the isoperimetric inequality. Oh. No, by Green's theorem. O i. d. O e. No, by the four vertex theorem. Oj. No, by Gauss' Theorema Egregium. Ok. No, by the Gauss-Bonnet theorem.
