40. Since the thermal density matrix in Eq. (57) weights the final and not the initial positions of the classical paths, one might be inclined to say that Eq. (57) is not a complete IVR for the semiclassical time-correlation function.

46. Of course, if our system contains many degrees of freedom and  and B̂ are operators pertaining to just a few of them, then we could say that our system is composed of a subsystem of interest coupled to a bath; however, in Herman and Coker's analysis the degrees of freedom of the bath are not integrated over in the correlation function.
47. t. Therefore, if this generalization is possible, then the derivation of a mixed quantumclassical time-correlation function would need to incorporate an influence functional to some extent to achieve decoherence. Obviously, we have not examined such a generalization in this article: it is a conjecture.
