Anti-Ramsey numbers in complete split graphs

چکیده

A subgraph of an edge-coloured graph is rainbow if all of its edges have different colours. For graphs G and H the anti-Ramsey number ar(G,H) is the maximum number of colours in an edge-colouring of G with no rainbow copy of H. The notion was introduced by Erdős, Simonovits and V. Sós and studied in case G = Kn. Afterwards exact values or bounds for anti-Ramsey numbers ar(Kn, H) were established for various H among others by Alon, Jiang & West, Montellano-Ballesteros & Neumann-Lara, Schiermeyer. There are also results concernig bipartite graphs, cubes or product of cycles as G obtained by Axenovich, Li, Montellano-Ballesteros, Schiermeyer and others. In the talk we give the survey of these results and also there will be presented numerous results with a complete split graph Kn + Km as the host graph G.

Generalized Split Graphs and Ramsey Numbers

A graph G is called a ( p, q)-split graph if its vertex set can be partitioned into A, B so that the order of the largest independent set in A is at most p and the order of the largest complete subgraph in B is at most q. Applying a well-known theorem of Erdo s and Rado for 2-systems, it is shown that for fixed p, q, ( p, q)-split graphs can be characterized by excluding a finite set of forbidd...

Ramsey numbers in complete balanced multipartite graphs. Part II: Size numbers

The notion of a graph theoretic Ramsey number is generalised by assuming that both the original graph whose edges are arbitrarily bi–coloured and the sought after monochromatic subgraphs are complete, balanced, multipartite graphs, instead of complete graphs as in the classical definition. We previously confined our attention to diagonal multipartite Ramsey numbers. In this paper the definition...

Ramsey Numbers of K M versus (n; K)-graphs and the Local Density of Graphs Not Containing a K M

In this paper generalized Ramsey numbers of complete graphs K m versus the set h; n; ki of (n; k)-graphs are investigated. The value of r(K m ; hn; ki) is given in general for (relative to n) values of k small compared to n using a correlation with Turr an numbers. These generalized Ramsey numbers can be used to determine the local densities of graphs not containing a subgraph K m .

Ramsey Numbers R(K3, G) for Graphs of Order 10

In this article we give the generalized triangle Ramsey numbers R(K3, G) of 12 005 158 of the 12 005 168 graphs of order 10. There are 10 graphs remaining for which we could not determine the Ramsey number. Most likely these graphs need approaches focusing on each individual graph in order to determine their triangle Ramsey number. The results were obtained by combining new computational and th...
