Equilateral L-Contact Graphs,phs, drawing connections to Schnyder realizers and canonical orders of maximally planar graphs. We show that every contact system of L’s can always be converted to an equivalent one with equilateral L’s. This can be used to show a stronger version of a result of Thomassen, namely, that every planar

A number of graph parameters trying to capture this phenomenon and to measure these tree-like structures were proposed; most notable ones being the ., ., ., ., Gromov’s . of a graph, and . and . in a .

We then explain the main ideas behind an alternative approach introduced by Mömke and the author . The new ingredient in our approach is that it allows for the r

It follows that both linear rank-width and linear clique-width of forests can be computed in linear time. Using our characterization of linear rank-width of forests, we determine the set of minimal excluded acyclic vertex-mino
