Oriented Discrepancy of Hamilton cycles

Let G be an n-vertex graph of minimum degree δ(G) ≥ n/2, where n is sufficiently large. We show that for every ξ > 0 and every orientation of the edges of G, there exists a Hamilton cycle of $G$ with at least δ(G) - ξn edges oriented in accordance with the direction of the cycle. This proves an asymptotic version of a conjecture of Gishboliner, Krivelevich, and Michaeli.
This is joint work with Micha Christoph, Dan Hefetz and Stefanie Gerke
