Laplacian integral graphs with a given degree sequence constraint

Anderson Fernandes Novanta, Carla S. Oliveira, Leonardo S. de Lima

Let G be a graph on n vertices. The Laplacian matrix of G, denoted by L(G), is defined as L(G) = D(G) - A(G), where A(G) is the adjacency matrix of G and D(G) is the diagonal matri…
