Abstract

Balogh, Barát, Gerbner, Gyárfás, and Sárközy proposed the following conjecture. Let G be a graph on n vertices with minimum degree at least 3n/4. Then for every 2-edge-colouring of G, the vertex set V(G) may be partitioned into two vertex-disjoint cycles, one of each colour. We prove that this conjecture holds for n large enough, improving approximate results by the aforementioned authors and by DeBiasio and Nelsen.
