Pseudo Unique Sink Orientations

A unique sink orientation (USO) is a directed version of the hypercube graph $Q_n$ such that every induced subcube has a unique sink.

In this talk I will introduce the notion of a pseudo unique sink orientation (PUSO), a related class of objects arising naturally in the context of the USO recognition problem. I will derive many combinatorial properties of PUSOs, culminating in a characterization of their outmaps.
