coneSystem Q
The set of weights th for which the polytope (Q,th) is nonempty lies in a fan CQ. This fan is partitioned into cones by the walls of the toric quiver Q, and for each partition there exists a unique flow polytope. For a detailed discussion see Lutz Hille "Quivers, cones and polytopes", Linear algebra and its applications 365 (2003): 215-237.
