Abstract :
The aim of this paper is to first compute some bounds for forgotten
index and then to present spectral properties of this topological index.
In continuing, we define a new version of energy namely ISI energy
corresponding to the ISI index. Finally, we determine some bounds
for this new graph invariant.
