Small ramsey numbers
WebSmall Ramsey numbers. Preliminary version appeared as a technical report, Department of Computer Science, Rochester Institute of Technology, RIT-TR-93-008 (1993). Note: … WebA graph is d -degenerate if all its subgraphs have a vertex of degree at most d. We prove that there exists a constant c such that for all natural numbers d and r, every d -degenerate graph H of chromatic number r with V ( H) ≥ 2 d 2 2 c r has Ramsey number at most 2 d 2 c r V ( H) . This solves a conjecture of Burr and Erdős from 1973.
