A Note on Contractible Edges in Chordal Graphs
نویسندگان
چکیده
Contraction of an edge merges its end points into a new vertex which is adjacent to each neighbor of the end points of the edge. An edge in a k-connected graph is contractible if its contraction does not result in a graph of lower connectivity. We characterize contractible edges in chordal graphs using properties of tree decompositions with respect to minimal vertex separators.

A Note on Independence Complexes of Chordal Graphs and Dismantling
We show that the independence complex of a chordal graph is contractible if and only if this complex is dismantlable (strong collapsible) and it is homotopy equivalent to a sphere if and only if its core is a cross-polytopal sphere. The proof uses the properties of tree models of chordal graphs.
متن کاملA note on essentially left $phi$-contractible Banach algebras
In this note, we show that cite[Corollary 3.2]{sad} is not always true. In fact, we characterize essential left $phi$-contractibility of the group algebras in terms of compactness of its related locally compact group. Also, we show that for any compact commutative group $G$, $L^{2}(G)$ is always essentially left $phi$-contractible. We discuss the essential left $phi$-contractibility of some Fou...
متن کاملNecessary edges in k-chordalizations of graphs
In this note, we look at which edges must always be added to a given graph G = (V, E), when we want to make it a chordal graph with maximum clique size at most k by adding edges. lThis problem has a strong relation to the (algorithmic) theory of the treewidth of graphs. If {x, y} is an edge in every chordal supergraph of G with maximum clique size at most k, we call the pair necessary for treew...

متن کاملContractible Edges in 2-Connected Locally Finite Graphs
In this paper, we prove that every contraction-critical 2-connected infinite graph has no vertex of finite degree and contains uncountably many ends. Then, by investigating the distribution of contractible edges in a 2-connected locally finite infinite graph G, we show that the closure of the subgraph induced by all the contractible edges in the Freudenthal compactification of G is 2-arc-connec...
