Title: Eulerian partial duals of plane graphs


In the paper Bipartite partial duals and circuits in medial graphs, Huggett and Moffatt characterized bipartite partial duals of a plane graph using all-crossing directions of its medial graph and left 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 joint work with Metrose Metsidik.
