AB - We prove that every vertex v of a tournament T belongs to at least
$max{min{δ⁺(T), 2δ⁺(T) - d⁺_{T}(v) + 1}, min{δ¯(T), 2δ¯(T) - d¯_{T}(v) + 1}}$
arc-disjoint cycles, where δ⁺(T) (or δ¯(T)) is the minimum out-degree (resp. minimum in-degree) of T, and $d⁺_{T}(v)$ (or $d¯_{T}(v)$) is the out-degree (resp. in-degree) of v.
