Summary: We show that for outerplanar graphs \(G\) the problem of augmenting \(G\) by adding a minimum number of edges such that the augmented graph \(G'\) is planar and bridge-connected, biconnected, or triconnected can be solved in linear time and space.

On list‐coloring outerplanar graphs
Journal of Graph Theory, 2008AbstractWe prove that a 2‐connected, outerplanar bipartite graph (respectively, outerplanar near‐triangulation) with a list of colors L (v ) for each vertex v such that $|L(v)|\geq\min\{{\deg}(v),4\}$ (resp., $|L(v)|\geq{\min}\{{\deg}(v),5\}$) can be L‐list‐colored (except when the graph is K3 with identical 2‐lists).

A characterization of ?-outerplanar graphs
Journal of Graph Theory, 1996Chartrand and Harary have shown that if G is a non-outerplanar graph such that, for every edge e, both the deletion G\e and the contraction G/e of e from G are outerplanar, then G is isomorphic to K4 or K2,3. An α-outerplanar graph is a graph which is not outerplanar such that, for some edge α, both G\α and G/α are outerplanar.

Embedding Outerplanar Graphs in Small Books
SIAM Journal on Algebraic Discrete Methods, 1987A book consists of a number of half-planes (pages) sharing a common boundary line (the spine). A book embedding of a graph embeds the vertices on the spine and each edge in some page so that each page contains a plane subgraph. The width of a page is the maximum number of edges that intersect any half-line perpendicular to the spine in the page.

Farey Series and Maximal Outerplanar Graphs
SIAM Journal on Algebraic Discrete Methods, 1982Certain graphs representing Farey series of irreducible fractions are shown to be maximal outerplanar. For a suitable generalization of Farey series, the class of graphs obtained is exactly the class of maximal outerplanar graphs. Using a representation of maximal outerplanar graphs as series of irreducible fractions, efficient algorithms for deciding ...
