Pairs of trees in tree–tree triangulations
Discrete Mathematics, 2007 AbstractA triangulation T of a compact 2-manifold is said to be a tree–tree triangulation if the graph of T can be partitioned into two induced trees. Hence each tree–tree triangulation is a triangulation of the 2-sphere. Recognizing tree–tree triangulations among all simple spherical ones can be seen to be an NP-complete problem.
