Generalized Ramsey theory for graphs [PDF]

open access: yesBulletin of the American Mathematical Society, 1972
The classical Ramsey numbers [7] involve the occurrence of monochromatic complete subgraphs in line-colored complete graphs. By removing the completeness requirements and admitting arbitrary forbidden subgraphs within any given graph, the situation is ...

Generalized Ramsey theory VI: Ramsey numbers for small plexes [PDF]

open access: yesJournal of the Australian Mathematical Society, 1976
AbstractGeneralized Ramsey theory for graphs was formulated and developed in the previous papers in this series. We extend the area here by introducing generalized Ramsey numbers for higher dimensional simplicial complexes. In particular we calculate explicitly the Ramsey numbers for several small “pure 2-complexes”, or more brieflyplexes, in which ...

Generalized Ramsey theory for graphs XII: Bipartite Ramsey sets [PDF]

open access: yesGlasgow Mathematical Journal, 1981
Following the notation in Faudree and Schelp [3], we write G → (F, H) to mean that every 2-coloring of E(G), the edge set of G, contains a green (the first color) F or a red (the second color) H. Then the Ramsey number r(F, H) of two graphs F and H with no isolated vertices has been defined as the minimum p such that Kp → (F, H).

Generalized Ramsey theory for graphs. II. Small diagonal numbers [PDF]

open access: yesProceedings of the American Mathematical Society, 1972
Consider a finite nonnull graph G with no loops or multiple edges and no isolated points. Its Ramsey number r ( G ) r(G) is defined as the minimum number p such that every 2-coloring of the lines of the complete graph K p {K_p} must contain a ...

Generalized ramsey theory for graphs, x: double stars

open access: yesDiscrete Mathematics, 1979
AbstractThe double star S(n, m), where n ⩾ m ⩾ 0, is the graph consisting of the union of two stars K1,n and K1,m together with a line joining their centers. Its ramsey number r(S(n, m)) is the least number p such that there is a monochromatic copy of S(n, m) in any 2-coloring of the edges of Kp.
