A map [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] is said to be an isometric folding of [[??].sup.4] model into itself if and only if for any piecewise fuzzy geodesic path [gamma] : J [right arrow] [[??].sup.4] the induced path [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] is a piecewise fuzzy geodesic and of the same length as [gamma], where J = [0,1].
The Jacobi field for the Riemannian mean is equal to the sum of tangent vectors to all geodesics (from mean to each point).

In this paper, by taking both the local features and their connections into account, we propose a novel local shape feature representation method, geodesic connected graph, for 3D CAD model analysis.
Recall that in every free homotopy class there exists a single simple closed geodesic, assuming that punctures are simple closed geodesics with length equal to zero.
As a result, the scalar equation of isotropic geodesics (the equation of energy), in the "large scale approximation" in the globally non-holonomic space, gives the solution for the photon's energy (frequency) and the redshift z = [[omega].sub.0]-[omega]/[omega] " as depending on the distance r = ct travelled from the observer
Finally, Section 6 discusses very recent results about the structure of geodesics in the Brownian map.
Since our approach builds on the fact that a wave takes minimum energy path, when the assumption of isotropy in the media is imposed, the shortest energy path reduces to shortest distance path, which is provided by the evaluating the geodesics. Mathematically, the energy along a path is seen as weighing function defined along the path.
The concept can be extended to apply to open paths in Ray space where |[phi]([tau])> [??] |[phi](0)> by closing the curve by a geodesic, i.
