Academic Presentation 59° Congreso Nacional de la Sociedad Matemática Mexicana

Características Asintóticas de las Gráficas de Proximidad

Heriberto Espino-Montelongo

2026

Summary

Academic presentation connecting local geometric acceptance rules in proximity graphs with global probabilistic laws, using nearest-neighbor, Gabriel, relative-neighborhood, and Delaunay graphs as motivating examples.

Context

The presentation asks what global structure emerges when a local geometric proximity rule is repeatedly applied to a point cloud.

Main contributions

  • Introduces proximity graphs as geometric graphs whose edges are selected by local acceptance rules.
  • Compares nearest-neighbor, Gabriel, relative-neighborhood, and Delaunay structures on a common point set.
  • Connects local geometric definitions with asymptotic probabilistic behavior.
