Let G be a symmetric connected graph without loops. Denote by b (G) the maximum number of edges in a bipartite subgraph of G. Determination of b (G) is polynomial for planar graphs …
Consider the family of all finite graphs with maximum degree Δ (G)< d and matching number ν (G)< m. In this paper we give a new proof to obtain the exact upper bound for the number …
