TOP CONDENSATION WITHOUT FINE-TUNING

Quadratic divergencies which lead to the usual fine-tuning or hierarch y problem are discussed in top condensation models. As in the Standard Model a cancellation of quadratic divergencies is not possible withou t the boson contributions in the radiative corrections which are absen t in lowest order of an 1/N-c-expansion. To deal with the cancellation of quadratic divergencies we propose therefore an expansion in the fl avor degrees of freedom. In leading order we find the remarkable resul t that quadratic divergencies automatically disappear.
