Antipaths in oriented graphs

Klimosova, T; Stein M.

Keywords: Oriented graph, semidegree, Antidirected path

Abstract

We show that for any natural number k≥1, any oriented graph D of minimum semidegree at least (3k−2)/4 contains an antidirected path of length k. In fact, a slightly weaker condition on the semidegree sequence of D suffices, and as a consequence, we confirm a weakened antidirected path version of a conjecture of Addario-Berry, Havet, Linhares Sales, Thomassé and Reed.
