摘要
Let D = (V1, V2; A) be a directed bipartite graph with |V1| = |V2| = n ≥ 2. Suppose that dD(x) + dD(y) ≥ 3n for all x ∈ V1 and y ∈ V2. Then, with one exception, D contains two vertex-disjoint directed cycles of lengths 2n1 and 2n2, respectively, for any positive integer partition n = n1 + n2. This proves a conjecture proposed in [9].
