Abstract
We study the influence on the Fermi surface topology of many-body corrections beyond LDA. A Renormalized Band method is used to calculate the quasiparticle band structures of both CeAl3 and Ce3Al compounds. We discuss the conditions under which the LDA is expected to predict the correct Fermi surface.
