Resumen
CANO G., Leonardo A y CARRILLO, Sergio A. Can we detect Gaussian curvature by counting paths and measuring their length?. Integración - UIS [online]. 2020, vol.38, n.1, pp.33-42. Epub 27-Feb-2020. ISSN 0120-419X. https://doi.org/10.18273/revint.v38n1-2020003.
The aim of this paper is to associate a measure for certain sets of paths in the Euclidean plane ℝ2 with fixed starting and ending points. Then, working on parameterized surfaces with a specific Riemannian metric, we define and calculate the integral of the length over the set of paths obtained as the image of the initial paths in ℝ2 under the given parameterization. Moreover, we prove that this integral is given by the average of the lengths of the external paths times the measure of the set of paths if, and only if, the surface has Gaussian curvature equal to zero.
