Abstract. We investigate the collective oscillations of a Bose condensate
in an anisotropic harmonic trap. We analytically calculate
the values of the trap deformation for which the normal
modes are in resonance. In presence of low-order resonances,
the amplitude dependence of frequencies is strongly enhanced.
We also study the transition to chaos
of the collective modes as a function of the trap anisotropy.
