Abstract | Tree convex bipartite graphs generalize convex bipartite graphs by associating a tree, instead of a path, with one set of the vertices, such that for every vertex in another set, the neighborhood of this vertex induces a subtree. There are seven graph problems, grouped into three classes of domination, Hamiltonicity and treewidth, which are known to be -complete for bipartite graphs, but tractable for convex bipartite graphs. We show -completeness of these problems for tree convex bipartite graphs, even when the associated trees are stars or combs respectively. |
