摘要:In the paper [Bipartite partial duals and circuits in medial graphs, Combinatorica 33(2) (2013) 231-252]
Huggett and Moffatt characterized bipartite partial duals of a plane graph using all-crossing directions of its
medial graph and remained the characterization of Eulerian partial duals of a plane graph as an open problem.
In this talk we shall solve this problem by considering half-edge directions and allowing inconsistent edges.
This is a joint work with Metrose Metsidik
