The Path Partition Conjecture for digraphs states that for every digraph D, and every choice of positive integers λ 1 , λ 2 such that λ 1 + λ 2 equals the order of a longest directed path in D, there exists a partition of D in two subdigraphs D 1 , D 2 such that the order of the longest path in D i is at most λ i for i = 1, 2. We present sufficient(More)
A good drawing of Kn is a drawing of the complete graph with n vertices in the sphere such that: no two edges with a common end cross; no two edges cross more than once; and no three edges all cross at the same point. Gioan’s Theorem asserts that any two good drawings of Kn that have the same rotations of incident edges at every vertex are equivalent up to(More)
