A note on the independence number of triangle-free graphs
WebOur proof technique is an extension of a method of Caro [New Results on the Independence Number, Technical report, Tel Aviv University, 1979] and Wei [A Lower Bound on the Stability Number of a Simple Graph, TM 81-11217-9, Bell Laboratories, Berkley Heights, NJ, 1981], and we also give a new short proof of the main result of Caro … WebAbstract. Given a graph H, the Ramsey number r (H) is the smallest natural number N such that any two-colouring of the edges of K N contains a monochromatic copy of H.The existence of these numbers has been known since 1930 but their quantitative behaviour is still not well understood. Even so, there has been a great deal of recent progress on the … psychiatric nurse practitioner who jobs
On the independence number of random graphs - ScienceDirect
Websparse pseudo-random graphs. It should be stressed that the definition of pseudo-random graphs used in this study is rather restrictive and applies only to regular graphs. It seems plausible, however, that our techniques can be used to prove Hamiltonicity of almost regular graphs (i.e., graphs in which all degrees are very close to an average ... Web10 de abr. de 2024 · In this section, we consider the ratio-k-cuts of sparse graphs and prove Theorem 2. Note that a set of vertices in a graph G is independent if no two vertices from this set are joined by an edge. The independence number \(\alpha (G)\) is the maximum number of vertices in an independent set of G.
