Ramsey numbers of ordered graphs
An ordered graph is a pair $\mathcal{G}=(G,\prec)$ where $G$ is a graph and $\prec$ is a total ordering of its vertices. The ordered Ramsey number $\overline{R}(\mathcal{G})$ is the minimum number $N$ such that every ordered complete graph with $N ...

On the restricted size Ramsey number for P3 versus dense connected graphs
Let F, G and H be simple graphs. A graph F is said a (G,H)-arrowing graph if in any red-blue coloring of edges of F we can find a red G or a blue H. The size Ramsey number of G and H, ŕ(G,H), is the minimum size of F.

Diagonal Ramsey numbers in multipartite graphs related to stars
: Let the star on n vertices, namely K1, n − 1 be denoted by Sn. If every two coloring of the edges of a complete balanced multipartite graph Kj × s there is a copy of Sn in the first color or a copy of Sm in the second color, then we will say Kj × s ...

We present data which, to the best of our knowledge, includes all known nontrivial values and bounds for specific graph, hypergraph and multicolor Ramsey numbers, where the avoided graphs are complete or complete without one edge. Many results pertaining to other more studied cases are also presented.

Single Atom and Two Atom Ramsey Interferometry with Quantized Fields [PDF]
Implications of field quantization on Ramsey interferometry are discussed and general conditions for the occurrence of interference are obtained. Interferences do not occur if the fields in two Ramsey zones have precise number of photons. However in this

Generalization of Ramsey Number for Cycle with Pendant Edges
This paper explores various Ramsey numbers associated with cycles with pendant edges, including the classical Ramsey number, the star-critical Ramsey number, the Gallai–Ramsey number, and the star-critical Gallai–Ramsey number.

Critical Graphs for R(Pn, Pm) and the Star-Critical Ramsey Number for Paths
The graph Ramsey number R(G,H) is the smallest integer r such that every 2-coloring of the edges of Kr contains either a red copy of G or a blue copy of H.

On the Geometric Ramsey Number of Outerplanar Graphs
We prove polynomial upper bounds of geometric Ramsey numbers of pathwidth-2 outerplanar triangulations in both convex and general cases. We also prove that the geometric Ramsey numbers of the ladder graph on $2n$ vertices are bounded by $O(n^{3})$ and $O(

Summary: The planar Ramsey number \(\text{PR}(G, H)\) is defined as the smallest integer \(n\) for which any 2-colouring of the edges of \(K_n\) with red and blue, where red edges induce a planar graph, leads to either a red copy of \(G\), or a blue copy of \(H\).

A Skills Gap Analysis of Farmer Directors of US Farmer Cooperatives
ABSTRACT Boards of directors are vital to firm performance and are an integral part of the decision‐making process of any business. Several studies have been conducted that observe corporate or nonprofit board characteristics, skills, and the board's connection to firm performance.
