WebWe can put them randomly in any set, and our graph would still be bipartite (or non-bipartite). Were you paying attention to the sum of degrees of the two sets? Theorem: In a bipartite graph, the sum of degrees of vertices of each set is equal to the number of edges. ∑ v ∈ A d e g ( v) = ∑ v ∈ B d e g ( v) = E . Why does it holds true? WebOct 15, 2024 · The sequence ( 1, − 1) obviously isn't graphical so the original sequence ( 4, 4, 4, 4, 2) can't be graphical. Note that we could have stopped once we reached ( 2, 2, 0) since this sequence clearly isn't graphical: there is no graph on 3 vertices such that one vertex has degree 0 and such that the other two vertices have degree 2.
