The edge-vertex inequality in a planar graph and a bipartition for the class of all planar graphs

M. R. Emamy-K., Bahman Kalantari, Tatiana Correa

For a planar graph with a given f-vector $(f_0,f_1,f_2),$ we introduce a cubic polynomial whose coefficients depend on the f-vector. The planar graph is said to be real if…
