Abstract:
A subgraph of an edge-colored graph is rainbow if all of its edges have different colors. For a given graph 𝐻, the anti-Ramsey number AR(𝑛,𝐻) of 𝐻 is the maximum number of colors in an edge-colored 𝐾𝑛 such that 𝐾𝑛 does not contain a copy of rainbow 𝐻. We determine the exactly anti-Ramsey number for paths. This confirms aconjecture posed by Erdös, Simonovits and Sós in 1970s.
