A detailed analytical description of the regions in the parameter space for which multiple small periodic solutions bifurcate from the equilibria of the system is obtained. As a consequence, a complete answer for the challenge proposed in [Moiola & Chua, 1999] is provided.497-515engChua's equationsLyapunov coefficientdegenerate Hopf bifurcationlimit cyclechaotic attractorArtigoWOS:000265940900003Acesso restrito3757225669056317
