Some extremal ratios of the distance and subtree problems in binary trees
Shuchao Li, Hua Wang, Shujing Wang
Among many topological indices of trees the sum of distances and the number of subtrees have been a long standing pair of graph invariants that are well known for the…

Further results on the expected hitting time, the cover cost and the related invariants of graphs
Jing Huang, Shuchao Li, Zheng Xie
A close relation between hitting times of the simple random walk on a graph, the Kirchhoff index, resistance-centrality, and related invariants of unicyclic graphs is displayed. Co…

Relation between the skew-rank of an oriented graph and the independence number of its underlying graph
J. Huang, S. C. Li, H. Wang
An oriented graph is a digraph without loops or multiple arcs whose underlying graph is . Let be the skew-adjacency matrix of and be the i…
