چکیده
A graph X is said to be chordal bipartite if it and contains no induced cycle of length at least 6. It proved that does not contain claw as an subgraph, then the Weisfeiler–Leman dimension most 3. This implies any permutation The proof based on theory coherent configurations.

Treewidth of Chordal Bipartite Graphs
Chordal bipartite graph are exactly those bipartite graph in which every cycle of length at least six has a chord. The treewidth of a graph G is the smallest maximum cliquesize among all chordal supergraphs of G decreased by one. We present a polynomial time algorithm for the exact computation of the treewidth of all chordal bipartite graphs. keywords: Graph algorithms, Algorithms and Data Stru...
متن کاملRecognizing Chordal-Bipartite Probe Graphs
A graph G is chordal-bipartite probe if its vertices can be partitioned into two sets P (probes) and N (non-probes) where N is a stable set and such thatG can be extended to a chordal-bipartite graph by adding edges between non-probes. A bipartite graph is called chordal-bipartite if it contains no chordless cycle of length strictly greater than 5. Such probe/non-probe completion problems have ...
متن کاملChordal Bipartite Bipartite
Several graph problems (e.g., steiner tree, connected domination, hamiltonian path, and isomorphismproblem), which can be solved in polynomialtime for distance-hereditary graphs, are NP-complete or open for parity graphs. Moreover, the metric characterizations of these two graph classes suggest an excessive gap between them. We introduce a family of classes forming an innnite lattice with respe...
متن کاملOn factorial properties of chordal bipartite graphs
For a graph property X, let Xn be the number of graphs with vertex set {1, . . . , n} having property X, also known as the speed of X. A property X is called factorial if X is hereditary (i.e. closed under taking induced subgraphs) and n1 ≤ Xn ≤ n2 for some positive constants c1 and c2. Hereditary properties with the speed slower than factorial are surprisingly well structured. The situation wi...
متن کاملBipartite Powers of k-chordal Graphs
Let k be an integer and k ≥ 3. A graph G is k-chordal if G does not have an induced cycle of length greater than k. From the definition it is clear that 3-chordal graphs are precisely the class of chordal graphs. Duchet proved that, for every positive integer m, if G is chordal then so is G. Brandstädt et al. in [Andreas Brandstädt, Van Bang Le, and Thomas Szymczak. Duchet-type theorems for pow...
