extended to the case of graphene [@Sharapov2004], where the difference only lies in the form the reduction factors take. In principle, this formula would be sufficient to describe the MO in the most general case, but due to its complexity it is not very useful. Thus, in general, limit cases are considered. The most familiar one is zero temperature an energy independent impurities, where the only reduction factor is the Dingle factor, in which case the infinite series can be easily evaluated. Another interesting situation is the pristine case (i.e. without impurities) at nonzero temperature. In this case the general series cannot yet be evaluated, due to the complicated temperature reducing factor, so in general some approximations are considered. The most prominent one is the limit $B\rightarrow0$ (low magnetic field), where one can simplify the temperature reduction factor and easily evaluate the infinite series. Nevertheless, one could argue that this limit may not be very useful, since the lower the magnetic field the more difficult is to observe the MO.

On the other hand, it is well known that when the Zeeman effect is considered, a splitting of the Landau levels appears, which is relevant for several thermodynamical properties [@Escudero2017].
