In the frame of the Hartree-Fock approximation, the dispersion of magnetoplasmons in Grapheme is derived for transitions implying the n = 0 Landau Level and those corresponding to the electron-hole transitions. It is shown that the electron-electron interactions lead to a strong re-nortnalization of the apparent Fermi velocity of Graphene which is different for both types of transitions.
