In the mathematical discipline of graph theory, the dual graph of a planar graph G is a graph that has a vertex for each face of G. The dual graph has an ... Dual polyhedra · Self-dual graphs · Properties · Weak dual |
A dual graph is defined for planar graphs, which do not necessarily have to be simple graphs, i.e. the original graph can contain loops and multiple edges. |
A graph derived from some plane graph in such a way that the derived graph has a vertex corresponding to each face of the given graph. |
3 дек. 2023 г. · A dual G. ∗ of a plane graph G is connected. Note. We can consider the dual of the dual of plane graph G (the “double dual”) of. G, G. |
