Abstract. We prove the cycle double cover conjecture, posed by Tutte, Itai and Rodeh, Szekeres, and Seymour, which asserts that every bridgeless undirected graph has a collection of cycles which covers every edge exactly twice. A cycle double cover of a graph is a multiset of cycles in which every edge occurs exactly twice. The conjecture was posed by Tutte [10], Itai and Rodeh [2], Szekeres ...
