Though real systems are never strictly closed, our present standpoint (also supported by numerical experience) implies that this should not be the pivotal point: Otherwise, standard Quantum Mechanics alone would not be sufficient to model the (entangled) time evolution, and, on the other hand, ESM would not be applicable to strictly closed systems. After including the most relevant perturbations “from outside” into the considered system, it must be possible to theoretically model it as strictly isolated from the rest of the world, with a well-defined Hamiltonian H H , possibly not known in detail but with generic properties

Since ρ ( t ) \rho(t) is non-negative and Hermitean, ( ψ , ϕ ) := ⟨ ψ | ρ ( t ) + ϵ | ϕ ⟩ (\psi,\phi):=\langle\psi|\rho(t)+\epsilon|\phi\rangle is a well defined scalar product for any ϵ > 0 \epsilon>0 . Hence, Cauchy-Schwarz’s inequality applies and by letting ϵ → 0 \epsilon\to 0 one obtains ( 6
