    Abstract: The energy of a digraph is defined as the sum of all real parts of its eigenvalues which are respect to its adjacency matrix. It is well known that graph energy is found that there are many applications in chemistry, physics and biology. In 2015, Gong and Gutman et al. proposed the concept of a borderenergetic graph. That is, if a graph G of order ... Show More
