Multiterminal flows in outerplanar networks

Journal of Algorithms, 1983
Abstract An outerplanar network is an undirected network whose underlying graph is a triangulation of a polygon. We give a linear algorithm for finding maximum flow values between all pairs of nodes in the outerplanar network. Our algorithm constructs the cut-tree of the outerplanar network without using any maximum flow computation.

On list‐coloring outerplanar graphs

Journal of Graph Theory, 2008
AbstractWe 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).

Independent covers in outerplanar graphs

1988
A subset U of vertices of a plane graph is said to be a perfect face-independent vertex cover (FIVC) if and only if each face has exactly one vertex in U. Necessary and sufficient conditions for a maximal plane graph to have a perfect FIVC are derived.

Proximity Drawings of Outerplanar Graphs.

1997
A proximity drawing of a graph is one in which pairs of adjacent vertices are drawn relatively close together according to some proximity measure while pairs of non-adjacent vertices are drawn relatively far apart. The fundamental question concerning proximity drawability is: Given a graph G and a definition of proximity, is it possible to construct a ...
