Forbidden graphs for degree and neighbourhood conditions
نویسنده
چکیده
For various graph-theoretic properties P that impose upper bounds on the minimum degree or the size of a neighbourhood set, we characterize the class %(P’) (%((P’)) of graphs G such that G and all its subgraphs (subcontractions) have property P. For example, if P is “6 <xn” (6 = minimum degree, n = number of vertices, 0 <X < 1) then S(P’) = F(K,+,), the class of graphs that do not have K,,, as a subgraph, where r = [l/(1 -x)]

On Hereditary Helly Classes of Graphs
In graph theory, the Helly property has been applied to families of sets, such as cliques, disks, bicliques, and neighbourhoods, leading to the classes of clique-Helly, disk-Helly, biclique-Helly, neighbourhood-Helly graphs, respectively. A natural question is to determine for which graphs the corresponding Helly property holds, for every induced subgraph. This leads to the corresponding classe...
متن کاملOn bounding the difference between the maximum degree and the chromatic number
For every k ∈ N0, we consider graphs in which for any induced subgraph, ∆ ≤ χ − 1 + k holds, and call this family of graphs Υk, where ∆ is the maximum degree and χ is the chromatic number of the subgraph. We give a finite forbidden induced subgraph characterization for every k. The results are compared to those given in [6], where the graphs in which for any induced subgraph, ∆ ≤ ω − 1 + k hold...
متن کاملBalanced Degree-Magic Labelings of Complete Bipartite Graphs under Binary Operations
A graph is called supermagic if there is a labeling of edges where the edges are labeled with consecutive distinct positive integers such that the sum of the labels of all edges incident with any vertex is constant. A graph G is called degree-magic if there is a labeling of the edges by integers 1, 2, ..., |E(G)| such that the sum of the labels of the edges incident with any vertex v is equal t...
متن کاملCharacterization and linear-time detection of minimal obstructions to concave-round graphs and the circular-ones property
A graph is concave-round if its vertices can be circularly enumerated so that the closed neighbourhood of each vertex is an interval in the enumeration. In this work, we give a minimal forbidden induced subgraph characterization for the class of concave-round graphs, solving a problem posed by Bang-Jensen, Huang, and Yeo [SIAM J Discrete Math, 13:179– 193, 2000]. In addition, we show that it is...
متن کاملA Magnetic Procedure for the Stability Number
A magnet is a pair u, v of adjacent vertices such that the proper neighbours of u are completely linked to the proper neighbours of v. It has been shown that one can reduce the graph by removing one of the vertices of a magnet together with all edges linking the other one to its proper neighbours without changing the stability number. We characterize a class of graphs such that by repeated use ...
