The outerplanar graphs are a subset of the planar graphs, the subgraphs of series–parallel graphs, and the circle graphs. The maximal outerplanar graphs, those to which no more edges can be added while preserving outerplanarity, are also chordal graphs and visibility graphs. Visa mer In graph theory, an outerplanar graph is a graph that has a planar drawing for which all vertices belong to the outer face of the drawing. Outerplanar graphs may be characterized (analogously to Visa mer An outerplanar graph is an undirected graph that can be drawn in the plane without crossings in such a way that all of the vertices belong to the unbounded face of the drawing. That is, no vertex is totally surrounded by edges. Alternatively, a graph G is … Visa mer Every outerplanar graph is a planar graph. Every outerplanar graph is also a subgraph of a series–parallel graph.

Visa mer Webb28 mars 2012 · An injective k-coloring of a graph is an assignment of colors to such that vertices having a common neighbor receive distinct colors. We study the list version of injective colorings of planar graphs. Let and be the injective choosability number and the maximum average degree of , respectively.
