Annulus graphs in $R^{d}$

Lyuben Lichev, Tsvetomir Mihaylov

A $d$ -dimensional annulus graph with radii $R_{1}$ and $R_{2}$ (here $R_{2} \geq R_{1} \geq 0$ ) is a graph embeddable in $R^{d}$ so that two vertices $u$ and $v$ form an edge if and only…

Outerspatial 2-complexes: Extending the class of outerplanar graphs to three dimensions

Johannes Carmesin, Tsvetomir Mihaylov

We introduce the class of outerspatial 2-complexes as the natural generalisation of the class of outerplanar graphs to three dimensions. Answering a question of O-joung Kwon, we pr…
