Abstract
Given two non-empty graphs G, H and a positive integer k, the Gallai–Ramsey number \({\text {gr}}_k(G:H)\) is defined as the minimum integer N such that for all \(n\ge N\), every k-edge-coloring of \(K_n\) contains either a rainbow colored copy of G or a monochromatic copy of H. In this paper, we got some exact values or bounds for \({\text {gr}}_k(P_5:H) \ (k\ge 3)\) if H is a general graph or a star with extra independent edges or a pineapple.
