摘要:

Let G be a simple graph and L(G) = D(G)A(G) be its Laplacian matrix, where A(G) and D(G) are the adjacency matrix and degree diagonal matrix.Then (G) = (L(G)+I n ) 1 is called the doubly stochastic matrix of G. Merris in 1998 proposed two conjectures and two problems of the doubly stochastic matrix, which are revealed some relations among, algebraic connectivity, the entry of(G) and graph structure. In this talk, we survey some progress and results on these conjectures and problems of Merris. In addition, some new problems are included
