“…(The same refers to its inverseQ.) This expectation is based on the recent consideration of the similar question for the quantum Hall effect of systems with interactions (see [66]). Notice, that radiative corrections to the CSE in QED calculated in [47] contain singularities in the limit of vanishing electron or photon mass.…”

“…In the present paper we do not consider interactions between the quasiparticles. It is worth mentioning that in the case of Integer Quantum Hall effect the similar problem has been considered recently (see [66]). It has been shown that the expression for Hall conductivity throughĜ has the same form as for the noninteracting case but withĜ replaced by the complete interacting Green function.…”

“…It is expected that in the presence of the inhomogeneous background (given by the inhomogeneous magnetic field, inhomogeneous rotation, etc) the corresponding conductivities will be given by the topological invariants in phase space composed of the Wigner transformed Green functions. This expectation is based on the recent extension of the topological representation for the Hall conductivity to the case of inhomogeneous magnetic field [17]. The representation of the non -dissipative conductivities in terms of the Wigner transformed propagators may repeat the corresponding homogeneous constructions with the ordinary product replaced by the Moyal product.…”
