Anti-Ramsey numbers of small graphs
arXiv:1310.4330
Abstract
The anti-Ramsey number ), for a graph and an integer , is defined to be the minimal integer such that in any edge-colouring of by at least colours there is a multicoloured copy of , namely, a copy of whose edges have distinct colours. In this paper we determine the anti-Ramsey numbers of all graphs having at most four edges.
