On the general position set of two classes of graphs
Yan Yao, Mengya He, Shengjin Ji +1
The general position problem is to find the cardinality of a largest vertex subset S such that no triple of vertices of S lie on a common geodesic. For a connected graph G, the car…

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…

Solution to a conjecture on the maximal energy of bipartite bicyclic graphs
Bofeng Huo, Shengjin Ji, Xueliang Li +1
The energy of a simple graph , denoted by , is defined as the sum of the absolute values of all eigenvalues of its adjacency matrix. Let denote the cycle of order $n…
