Artículo Minimum gradation in greyscales of graphs Castro Ochoa, Natalia de; Garrido Vizuete, María de los Angeles; Robles Arias, Rafael; Villar Liñán, María Trinidad (Elsevier, 2023) In this paper we present the notion of greyscale of a graph as a colouring of its vertices that uses colours from the real ...

Tesis Doctoral Teselaciones y Grafos de intersección Castro Ochoa, Natalia de; Cobos Gavala, Javier; Dana Jiménez, Juan Carlos (2002)
Artículo Triangle-Free Planar Graphs as Segment Intersection Graphs Castro Ochoa, Natalia de; Cobos Gavala, Javier; Dana Jiménez, Juan Carlos; Márquez Pérez, Alberto; Noy, Marc (2002) We prove that every triangle-free planar graph is the intersection graph of a set of segments in the plane. Moreover, the ...
