𝒫-Apex Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2018
Let 𝒫 be an arbitrary class of graphs that is closed under taking induced subgraphs and let 𝒞 (𝒫) be the family of forbidden subgraphs for 𝒫. We investigate the class 𝒫 (k) consisting of all the graphs G for which the removal of no more than k vertices ...

Odd 4-Coloring of Outerplanar Graphs

open access: yesGraphs and Combinatorics
A proper $k$-coloring of $G$ is called an odd coloring of $G$ if for every vertex $v$, there is a color that appears at an odd number of neighbors of $v$. This concept was introduced recently by Petruševski and Škrekovski, and they conjectured that every planar graph is odd 5-colorable.

Outerplanar Graphs and Delaunay Triangulations [PDF]

open access: yes, 2012
Dillencourt [1] showed that all maximal outerplanar graphs can be realized as Delaunay triangulations of points in convex position. In this note, we give two new, alternate proofs.
