چکیده
The size-Ramsey number $R^{(k)}(H)$ of a $k$-uniform hypergraph $H$ is the minimum edges in $G$ with property that each $2$-edge coloring contains monochromatic copy $H$. For $k\ge2$ and $n\in\mathbb{N}$, tight path on $n$ vertices $P^{(k)}_{n,k-1}$ defined as for which there an ordering its such edge set consists all $k$-element intervals consecutive this ordering. We show lower bound paths, is, considered assymptotically both uniformity $k$ $n$, $R^{(k)}(P^{(k)}_{n,k-1})= \Omega_{n,k}\big(\log (k)n\big)$.

The Size-ramsey Number
The size-Ramsey number of a graph G is the smallest number of edges in a graph Γ with the Ramsey property for G, that is, with the property that any colouring of the edges of Γ with two colours (say) contains a monochromatic copy of G. The study of size-Ramsey numbers was proposed by Erdős, Faudree, Rousseau, and Schelp in 1978, when they investigated the size-Ramsey number of certain classes o...
متن کاملThe Size Ramsey Number
Let i2 denote the class of all graphs G which satisfy G-(Gl, GE). As a way of measuring r inimality for members of P, we define the Size Ramsey number ; We then investigate various questions concerned with the asymptotic behaviour of r .
متن کاملOn the Size-Ramsey Number of Hypergraphs
The size-Ramsey number of a graph G is the minimum number of edges in a graph H such that every 2-edge-coloring of H yields a monochromatic copy of G. Size-Ramsey numbers of graphs have been studied for almost 40 years with particular focus on the case of trees and bounded degree graphs. We initiate the study of size-Ramsey numbers for k-uniform hypergraphs. Analogous to the graph case, we cons...
متن کاملA lower bound on the size of resolution proofs of the Ramsey theorem
We prove an exponential lower bound on the lengths of resolution proofs of propositions expressing the finite Ramsey theorem for pairs. Assuming that n ≥ R(k), where R(k) denotes the Ramsey number, the Ramsey theorem for pairs and two colors, n→ (k)2, is presented by the following unsatisfiable set of clauses. The variables are xij, for 1 ≤ i < j ≤ n. The clauses are ∨ i,j∈K xij and ∨ i,j∈K ¬xi...
متن کاملThe vertex size-Ramsey number
In this paper, we study an analogue of size-Ramsey numbers for vertex colorings. For a given number of colors r and a graph G the vertex size-Ramsey number of G, denoted by R̂v(G, r), is the least number of edges in a graph H with the property that any r-coloring of the vertices of H yields a monochromatic copy of G. We observe that Ωr(∆n) = R̂v(G, r) = Or(n ) for any G of order n and maximum deg...
