摘要：

In the frame of the Hartree-Fock approximation, the dispersion of magnetoplasmons in graphene is derived for all types of transitions for filling factors nu <= 6. The optical conductivity components of the magnetoplasmon curves are calculated. It is shown that the electron-electron interactions lead to a strong renormalization of the apparent Fermi velocity of graphene, which is different for different types of transitions.
