The size-Ramsey number of a graph 
denoted by is the smallest integer 
such that there is a graph with edges with this property that for any coloring of the edges of 
with
colors, contains a monochromatic copy of
. The investigation of the size-Ramsey numbers of graphs was initiated by Erdős‚ Faudree‚ Rousseau and Schelp in 1978. Since then, Size-Ramsey numbers have been studied with particular focus on the case of trees and bounded degree graphs.
Addressing a question posed by Erdős‚ Beck [2] proved that the size-Ramsey number of the path
is linear in 
by means of a probabilistic construction. In fact, Beck’s proof implies that and this upper bound was improved several times. Currently‚ the best known upper bound is due to Dudek and Prałat [4] which proved that . On the other hand‚ the first nontrivial lower bound for was provided by Beck and his result was subsequently improved by Dudek and Prałat [3] who showed that. The strongest known lower bound was proved recently by Bal and DeBiasio [1].
