Representaciones Circulares de Grafos Simples Conexos y el Rango Mínimo Semidefinido de un Delta Grafo
Pedro Díaz Navarro
In this paper we give a technique to represent simple connected graphs by using Clockwise Circular Representations and we show its applications by calculating orthogonal representa…
