Induced Ramsey Numbers

COMBINATORICA, 1998
The induced Ramsey number \(r_{\text{ind}}(G,H)\), is the smallest possible order of a graph \(F\) with the property that if the edges of \(F\) are \(2\)-colored, there is an induced subgraph of \(G\) in the first color or \(H\) in the second color.

Distance ramsey numbers

Doklady Mathematics, 2013
A graph is a distance graph in \(R^d,\) the \(d\)-dimension Euclidean space, if its vertices can be associated with different points of \(R^d\) such that any pair of adjacent vertices of such a graph corresponds to a pair of points a unit distance apart.

Gameboard Ramsey Numbers

2005
Sequences Bn(p,q) of connected parts of Euclidean and hyperbolic (p,q)-mosaic graphs are considered. The smallest n such that any 2-coloring of the edges of Bn( p,q) contains a given monochromatic graph G is introduced as gameboard Ramsey number rp,q(G). For p ≥ 4 it is proved that these Ramsey numbers exist for finitely many graphs only.

Ramsey Numbers

1998
Abstract The (diagonal) Ramsey number r(G) of a single graph G is the Ramsey number r(G, G). On pages 374—379 we depict all isolate-free graphs with up to 7 edges, with their Ramsey numbers. The R-number appearing in each top-right comer is the serial number of the graph in Burr’s catalogue; a graph that appears elsewhere in this Atlas ...

Mixed Ramsey Numbers Revisited

Combinatorics, Probability and Computing, 2003
Given a graph Hwith no isolates, the (generalized) mixed Ramsey number is the smallest integer r such that every H-free graph of order r contains an m-element irredundant set. We consider some questions concerning the asymptotic behaviour of this number (i) with H fixed and , (ii) with m fixed and a sequence of dense graphs, in particular for the ...
