On extremal leaf status and internal status of trees
Haiyan Guo, Bo Zhou
For a vertex of a tree , the leaf (internal, respectively) status of is the sum of the distances from to all leaves (internal vertices, respectively) of . The min…
Minimum status, matching and domination of graphs
Caixia Liang, Bo Zhou, Haiyan Guo
The minimum status of a graph is the minimum of statuses of all vertices of this graph. We give a sharp upper bound for the minimum status of a connected graph with fixed order and…
On the distance -spectral radius of a connected graph
H. Y. Guo, B. Zhou
For a connected graph and , the distance -spectral radius of is the spectral radius of the matrix defined as , where …
Uniform hypergraphs with the first two smallest spectral radii
Jianbin Zhang, Jianping Li, Haiyan Guo
The spectral radius of a uniform hypergraph is the the maximum modulus of the eigenvalues of the adjacency tensor of . For , among connected -uniform hypergraphs…
On the -spectral radius of uniform hypergraphs
HaiYan Guo, Bo Zhou
For and a uniform hypergraph , the -spectral radius of is the largest -eigenvalue of , where and $\mat…
On the -spectral radius of graphs
Haiyan Guo, Bo Zhou
For , Nikiforov proposed to study the spectral properties of the family of matrices of a graph , where is the degree diagonal matrix…
