A conjecture of Thomassen from 1982 states that, for everythere is anso that every strongly-connected tournament containsedge-disjoint Hamilton cycles. A classical theorem of Camion, that every strongly connected tournament contains a Hamilton cycle, implies that. So far, even the existence ofwas open. In this paper, we prove Thomassen's conjecture by showing that. This is best possible up to the logarithmic factor. As a tool, we show that every strongly-connected tournament is-linked (which improves a previous exponential bound). The proof of the latter is based on a fundamental result of Ajtai, Komlós and Szemerédi on asymptotically optimal sorting networks.
