Journal for Geometry and Graphics 19 (2015), No. 2, 179--188 Copyright Heldermann Verlag 2015 A Property of Liouville Surfaces and Manifolds Calin-Serban Barbat Dieselstr. 19, 80993 München, Germany calin.barbat@web.de We use the definition of the energy of a curve on a surface and show that in a Liouville surface the energy integrals along the diagonals of a net rectangle (Liouville maps are conformal) are equal. This result allows a generalization to Liouville manifolds, which is stated and proved in this paper. A series of different surfaces with an induced Liouville metric are given in Euclidean spaces. One example is given in the pseudo-Euclidean (Minkowski) plane. The material presented here also relates to our previous article in this journal [Journal of Geometry and Graphics 18 (2014) 7--21]. Keywords: Energy/action of curve, Liouville metric, Liouville surface, Liouville manifold. MSC: 53A05; 53A07 [ Fulltext-pdf (241 KB)] |
