Abstrak
In a recent preprint cond-mat/9906450 (published in PRL 84, 3141 (2000)) Bodo Huckestein showed that at real experimental conditions it is not possible to observe the quantum Hall effect (QHE) at $ω_{c}τ<1$ predicted by Khmelnitskii ($ω_{c}=eB/m$ is the cyclotron frequency and $τ$ is the scattering time). We would like to point out here that in fact the situation is not so hopeless due to the influence of the electron-electron interaction.
