Fractional chromatic number of one class of distance graphs
Xue Sheng-wei · Journal of Shandong University · 2008
The fractional chromatic number of the distance graph G(Z,Dm,k,k+1,k+2,k+3)(where Dm,k,k+1,k+2,k+3={1,2,…,m}-{k,k+1,k+2,k+3}) and its chromatic number for some pairs of integers,when 2k≤m≤2k+5 were discussed.
