Contact graphs of boxes with unidirectional contacts

Daniel Gonçalves, Vincent Limouzy, Pascal Ochem

This paper is devoted to the study of particular geometrically defined intersection classes of graphs. Those were previously studied by Magnant and Martin, who proved that these gr…

Properties of a Ternary Infinite Word

James Currie, Pascal Ochem, Narad Rampersad +1

We study the properties of the ternary infinite word p = 012102101021012101021012 ... , that is, the fixed point of the map h:0->01, 1->21, 2->0. We determine its factor complexity…

Oriented coloring of graphs with low maximum degree

Pascal Ochem, Alexandre Pinlou

Duffy et al. [C. Duffy, G. MacGillivray, and É. Sopena, Oriented colourings of graphs with maximum degree three and four, Discrete Mathematics, 342(4), p. 959--974, 2019] recently…

Partitioning sparse graphs into an independent set and a graph with bounded size components

Ilkyoo Choi, François Dross, Pascal Ochem

We study the problem of partitioning the vertex set of a given graph so that each part induces a graph with components of bounded order; we are also interested in restricting these…

Repetition avoidance in products of factors

Pamela Fleischmann, Pascal Ochem, Kamellia Reshadi

We consider a variation on a classical avoidance problem from combinatorics on words that has been introduced by Mousavi and Shallit at DLT 2013. Let be the su…

Vertex partitions of -free planar graphs

François Dross, Pascal Ochem

A graph is -colorable if its vertex set can be partitioned into a graph with maximum degree at most and and a graph with maximum degree at most . We show that…
