If L1 and L2 are linear equations, then the disjunctive Rado number of the set {L1,L2} is the least integer n, provided that it exists, such that for every 2-coloring of the set {1,2,…,n} there exists a monochromatic solution to either L1 or L2. If such an integer n does not exist, then the disjunctive Rado number is infinite. In this paper, it is shown that for all integers a⩾1and b⩾1, the disjunctive...
