The authors analyze some qualitative properties of a global solution to the Cauchy problem for the equation \(u_{tt}-\Delta u+\lambda u\left| u\right| ^{\frac{4}{n-2}}=0\) in both focusing and defocusing case, provided that such a global solution exists and satisfies the conservation of energy. They describe the asymptotic behavior of several energies as a consequence of a family of energy identities satisfied by the global solution of the above equation.
