Abstract: Adirected graph is semi-transitive if and only if it is acyclic and for any directed path u1 →u2 →···→ut, t ≥2, either there is no edge from u1 to ut or all edges ui → uj exist for 1 ≤ i < j ≤t. An undirected graph is semi-transitive if it admits a semi-transitive orientation. Recognizing semi-transitive orientability of a graph is an NP-complete problem. Asplit graph is a graph in which the vertices can be partitioned into a clique and an independent set. Semi-transitive orientability of split graphs was recently studied in a series of papers in the literature. The main result in this paper is proving that recognition of semi-transitive orientability of split graphs can be done in a polynomial time.
