Abstract
In this work we have adapted the Mahan-Nozieres-De Dominicis formalism to study the characteristics of both emission and absorption spectra of a doped two-dimensional system at zero temperature and under both a perpendicular magnetic field and a periodic lateral modulation. Since the electron-hole interaction depends on the hole coordinates, we hav e analysed how the hole position modifies both emission and absorption spectra for filling factor nu = 1 and nu = 1/2.
