On the minimal energy of tetracyclic graphs
Hongping Ma, Yongqiang Bai
The energy of a graph is defined as the sum of the absolute values of the eigenvalues of its adjacency matrix. In this paper, we characterize the tetracyclic graph of order wit…
On the minimal energy of conjugated unicyclic graphs with maximum degree at most 3
Hongping Ma, Yongqiang Bai, Shengjin Ji
The energy of a graph , denoted by , is defined as the sum of the absolute values of all eigenvalues of . Let be an even number and be the set of a…
The matching energy of graphs with given edge connectivity
Shengjin Ji, Hongping Ma
Let G be a simple graph of order and the roots of its matching polynomial. The matching energy of is defined as the sum . Let $K_{n-…
All Connected Graphs with Maximum Degree at Most 3 whose Energies are Equal to the Number of Vertices
Xueliang Li, Hongping Ma
The energy of a graph is defined as the sum of the absolute values of its eigenvalues. Let be the star of order 2 (or ) and be the graph obtained from $S_…
A proof of the conjecture on hypoenergetic graphs with maximum degree
Xueliang Li, Hongping Ma
The energy of a graph is defined as the sum of the absolute values of its eigenvalues. A graph of order is said to be hypoenergetic if . Majstorović et a…
Hypoenergetic and strongly hypoenergetic trees
Xueliang Li, Hongping Ma
The energy of a graph is defined as the sum of the absolute values of the eigenvalues of . An -vertex graph is said to be hypoenergetic if and strongly hy…
