Maxima of the signless Laplacian spectral radius for planar graphs
Guanglong Yu
The signless Laplacian spectral radius of a graph is the largest eigenvalue of its signless Laplacian. In this paper, we prove that the graph has the maximal…

On the local base set of primitive and nonpowerful signed digraphs
Guanglong Yu, Zhengke Miao
In this paper, we consider the local bases of primitive nonpowerful sign pattern matrices, show that there are "gaps" in the local base set and characterize some sign pattern matri…
