A Note on Some Generalizations of Monge's Theorem
Journal for geometry and graphics, Tome 25 (2021) no. 2, pp. 227-23
We generalize Monge's theorem for n+1 pairwise homothetic sets (in particular convex bodies) in En in place of three disks in E2. We also present a version for homotheties for pairs of vertices of a non degenerate simplex in En. It includes a reverse of Monge's theorem. Moreover, we give an analogon of Monge's theorem for the n-dimensional sphere and hyperboloid model of the hyperbolic space.
