Abstract
We consider -orientations, which are defined to be orientations of -regular graphs such that every vertex either has in-degree or out-degree . These generalise the orientations considered in Jaeger's conjecture, where . Working with random -regular graphs using the small subgraph conditioning method, we prove that a -regular graph has a -orientation with high probability for several values of , including the cases of Jaeger's conjecture (known to be deterministically false). Some negative results are obtained by exploiting a connection with maximum bisection size.
