Abstract

Given a graph GG and a positive integer kk, the \emph{Gallai-Ramsey number} is defined to be the minimum number of vertices nn such that any kk-edge coloring of KnK_n contains either a rainbow (all different colored) triangle or a monochromatic copy of GG. In this paper, we obtain general upper and lower bounds on the Gallai-Ramsey numbers for books Bm=K2+KmB_{m} = K_{2} + \overline{K_{m}} and prove sharp results for m5m \leq 5.
