Restricted size Ramsey number for path of order three versus graph of order five
نویسندگان
چکیده
Let G and H be simple graphs. The Ramsey number r(G,H) for a pair of graphs G and H is the smallest number r such that any red-blue coloring of the edges of Kr contains a red subgraph G or a blue subgraph H . The size Ramsey number r̂(G,H) for a pair of graphs G and H is the smallest number r̂ such that there exists a graph F with size r̂ satisfying the property that any red-blue coloring of the edges of F contains a red subgraph G or a blue subgraph H . Additionally, if the order of F in the size Ramsey number equals r(G,H), then it is called the restricted size Ramsey number. In 1983, Harary and Miller started to find the (restricted) size Ramsey numbers for pairs of small graphs with orders at most four. Faudree and Sheehan (1983) continued Harary and Miller’s works and summarized the complete results on the (restricted) size Ramsey numbers for pairs of small graphs with orders at most four. In 1998, Lortz and Mengenser gave both the size Ramsey numbers and the restricted size Ramsey numbers for pairs of small forests with orders at most five. To continue their works, we investigate the restricted size Ramsey numbers for a path of order three versus any connected graph of order five.

On the Ramsey Numbers for a Combination of Paths and Jahangirs
For given graphs G and H, the Ramsey number R(G, H) is the least natural number n such that for every graph F of order n the following condition holds: either F contains G or the complement of F contains H. In this paper, we improve the Surahmat and Tomescu’s result [9] on the Ramsey number of paths versus Jahangirs. We also determine the Ramsey number R(∪G, H), where G is a path and H is a Jah...
متن کاملThe Ramsey numbers of large trees versus wheels
For two given graphs G1 and G2, the Ramseynumber R(G1,G2) is the smallest integer n such that for anygraph G of order n, either $G$ contains G1 or the complementof G contains G2. Let Tn denote a tree of order n andWm a wheel of order m+1. To the best of our knowledge, only R(Tn,Wm) with small wheels are known.In this paper, we show that R(Tn,Wm)=3n-2 for odd m with n>756m^{10}.
متن کاملRamsey numbers for small graphs versus small disconnected graphs
The Ramsey number r(G,H) is determined for all disconnected (isolatefree) graphs H of order six and all graphs G of order at most five, except the three cases (G,H) ∈ {(K5 − 2K2, 2K3), (K5 − e, 2K3), (K5, 2K3)} where bounds with difference 1 are established. Moreover, general results are obtained for some small disconnected graphs H and any graph G.
متن کاملGraphs with partial order competition dimensions greater than three
Choi et al. [2] introduced the notion of the partial order competition dimension of a graph and studied graphs whose partial order competition dimensions are less than or equal to three. In this paper, we present two interesting families of graphs whose partial order competition dimensions are greater than three. In the process, particularly, a variety of notions such as Ramsey number, graph or...
