For given simple graphs H1β,H2β,β¦,Hcβ, the Ramsey number
r(H1β,H2β,β¦,Hcβ) is the smallest positive integer n such that
every edge-colored Knβ with c colors contains a subgraph isomorphic to
Hiβ in color i for some iβ{1,2,β¦,c}. A critical graph of
r(H1β,H2β,β¦,Hcβ) is an edge-colored complete graph on
r(H1β,H2β,β¦,Hcβ)β1 vertices with c colors which contains no subgraph
isomorphic to Hiβ in color i for any iβ{1,2,β¦,c}. For
n1ββ₯n2ββ₯β¦β₯ncββ₯1, Cockayne and Lorimer (The Ramsey number
for stripes, J. Austral. Math. Soc. 19 (1975) 252--256.) showed that
r(n1βK2β,n2βK2β,β¦,ncβK2β)=n1β+1+i=1βcβ(niββ1), in which niβK2β is a matching of size
niβ. In this paper, using Gallai-Edmonds Structure Theorem, we give a new
proof on the value of r(n1βK2β,n2βK2β,β¦,ncβK2β) which also
characterized all critical graphs
