Flips in combinatorial pointed pseudo-triangulations with face degree at most four
Oswin Aichholzer, Thomas Hackl, David Orden +3
In this paper we consider the flip operation for combinatorial pointed pseudo-triangulations where faces have size 3 or 4, so-called combinatorial 4-PPTs. We show that every combin…

Geometric achromatic and pseudoachromatic indices
O. Aichholzer, G. Araujo-Pardo, N. García-Colín +4
The pseudoachromatic index of a graph is the maximum number of colors that can be assigned to its edges, such that each pair of different colors is incident to a common vertex. If…
