Abstract:

A graph H = (W, E-H) is said to have bandwidth at most b if there exists a labeling of W as w(1), w(2), . . . , w(n) such that vertical bar i - j vertical bar <= b for every edge w(i)w(j) is an element of E-H, and a bipartite balanced (beta, Delta)-graph H is a bipartite graph with bandwidth at most beta vertical bar W vertical bar and maximum degree at most Delta, and furthermore it has a proper 2- coloring chi : W -> [2] such that vertical bar vertical bar chi(-1)(1)vertical bar - vertical bar chi(-1)(2)vertical bar vertical bar <= beta vertical bar chi(-1)(2)vertical bar. We prove that for any fixed 0 < gamma < 1 and integer Delta >= 1, there exist a constant beta = beta(gamma, Delta) > 0 and a natural number n(0) such that for every balanced (beta, Delta)-graph H on n >= n(0) vertices the bipartite Ramsey number br(H, H) is at most (1 + gamma)n. In particular, br(C-2(n), C-2n) = (2 + o(1))n.
