RESUMO

In this work, we calculate the ratio between the susceptibility amplitudes above and below the critical temperature associated with the m-axial Lifshitz point. We get results to first order in the perturbative loop expansion. We show that the ratio value between the amplitudes for the anisotropic case generalizes the known result for the m = 1 case. The ratio for the isotropic case was obtained for the first time. The obtained results are shown to be universal
