Matching extension and distance spectral radius
Yuke Zhang, Edwin R. van Dam
A graph is called -extendable if each -matching can be extended to a perfect matching. We give spectral conditions for the -extendability of graphs and bipartite graphs us…

Graphs with three distinct distance eigenvalues
Yuke Zhang, Huiqiu Lin
In this paper, some special distance spectral properties of graphs are considered. Concretely, we recursively construct an infinite family of trees with distance eigenvalue , a…
