The Laplacian spectrum, Kirchhoff index and complexity of the linear heptagonal networks
Jia-Bao Liu, Jing Chen, Jing Zhao +1
Let be the linear heptagonal networks with heptagons. We study the structure properties and the eigenvalues of the linear heptagonal networks. According to the Laplacian…
Changing and unchanging 2-rainbow independent domination
Pu Wu, Zehui Shao, Vladimir Samodivkin +3
For a function we denote by the set of vertices to which the value is assigned by , i.e. . If…
On the largest -spectral radius of cacti
Shaohui Wang, Chunxiang Wang, Jia-Bao Liu +1
Let be the adjacent matrix and the diagonal matrix of the degrees of a graph , respectively. For , the matrix is…
The characterization of perfect Roman domination stable trees
Zepeng Li, Zehui Shao, Yongsheng Rao +2
A \emph{perfect Roman dominating function} (PRDF) on a graph is a function satisfying the condition that every vertex for which $f(…
On the sharp lower bounds of Zagreb indices of graphs with given number of cut vertices
Shengjin Ji, Shaohui Wang
The first Zagreb index of a graph is the sum of the square of every vertex degree, while the second Zagreb index is the sum of the product of vertex degrees of each edge over a…
On the maximum and minimum multiplicative Zagreb indices of graphs with given number of cut edges
Shaohui Wang, Chunxiang Wang, Lin Chen
For a molecular graph, the first multiplicative Zagreb index is equal to the product of the square of the degree of the vertices, while the second multiplicative Zagreb index…
