Web2 and how well-connected the graph is, the symmetric formulation of the Laplacian spread conjecture in (3) can be interpreted as stating that a graph and its complement cannot both be very poorly connected. ∗Department of Mathematics, Brigham Young University, Provo, UT, [email protected] Webthe complement of C 4 is a 1 -regular graph, it is a matching. Let G be a regular graph, that is there is some r such that δ G ( v) = r for all v ∈ V ( G). Then, we have δ G ¯ ( v) = n − r − 1, where G ¯ is the complement of G and n = V ( G) . Hence, the complement of G is also regular. philips 55oled935/79
