WebEulerian and bipartite graph is a dual symmetric concept in Graph theory. It is well-known that a plane graph is Eulerian if and only if its geometric dual is bipartite. In this paper, we generalize the well-known result to embedded graphs and partial duals of cellularly embedded graphs, and characterize Eulerian and even-face graph partial duals of a … WebIn graph theory, a planar graph is a graph that can be embedded in the plane, i.e., it can be drawn on the plane in such a way that its edges intersect only at their endpoints. In …
WebFeb 22, 2024 · 1. This type of coloring is called a vertex-edge-face coloring in this paper, where the same conjecture is made: that for any planar graph G with maximum degree Δ, χ v e f ( G) ≤ Δ + 4, where χ v e f is the vertex-edge-face chromatic number. (Actually, the paper's Conjecture 1 goes further and makes this conjecture for list coloring.)
