    • Ref. 14 the linear assumption used in Ref. 13 is shown to be wrong, essentially because a realistic system cannot be linear in the force (Formula presented) at a microscopic level, due to the chaotic nature of the phase space trajectories. In the linear response scheme developed in the present paper the linearization is introduced solely by the construction of the initial distribution Eq. (21), while the time evolution of the phase space probability is evaluated from unperturbed (autonomous), Hamiltonian or general stochastic dynamics, thus avoiding the assumption of microscopic linearity

    • A proper dynamic definition of temperature should at least give exactly the microcanonical temperature (Formula presented) when averaged 27. This is why the number of kinetic degrees of freedom becomes important. However, it is unclear exactly how much the number of kinetic degrees of freedom is reduced by the isoenergetic constraint, except that it must be a number around 1, depending on the potential
