A proof of the two-path conjecture
The electronic journal of combinatorics, Tome 9 (2002)
Let $G$ be a connected graph that is the edge-disjoint union of two paths of length $n$, where $n\ge2$. Using a result of Thomason on decompositions of 4-regular graphs into pairs of Hamiltonian cycles, we prove that $G$ has a third path of length $n$.
