WebOct 20, 2024 · The case H is 3-vertex path is well known under the name cluster vertex deletion ( cluster-vd for short). Very recently, the COCOON 2024 paper [ 1] addresses the case H is the claw K_ {1,3}, the complete bipartite graph with 1 and 3 vertices in each part, thus the claw-vd problem.

WebJan 1, 2024 · It will be helpful in investigating graphs with at least one cut-vertex to consider the block-cut tree of a graph G. The vertex set of is the union of the cut-vertices of G and the blocks, i.e., the maximal 2-connected components, of G. … WebNov 2, 2024 · For every connected graph G there is a tree whose nodes are the blocks and the cut-vertices of G, sometimes called the block-cut tree, that is obtained by adding an edge between every block B and every cut-vertex v such that v \in B. The block-cut tree of a given connected graph G can be computed in linear time [ 24 ].
WebThe following characterization of the block cut-vertex graphs is well known. Theorem 1:1 (F. Harary and G. Prins, [3]) A graph Gis the block cut-vertex graph of some graph Hif and only if it is a tree in which the distance between any two end vertices is even. In view of Theorem 1.1, the author in [5] will speak of the block vertex tree of a graph.
