Embedding Quartic Eulerian Digraphs on the Plane
[article]
2017
arXiv
pre-print
Minimal obstructions for embedding 4-regular Eulerian digraphs on the plane are considered in relation to the partial order defined by the cycle removal operation. Their basic properties are provided and all obstructions with parallel arcs are classified.
